Yellowheart Wood Pen Blanks - Vibrant Yellow Exotic Hardwood

Product Specifications

Blank Sizes: Each pen blank is a minimum of 5" long × 3/4" × 3/4" square.

Material: Genuine Yellowheart (Euxylophora paraensis) — a bright, vibrant South American exotic hardwood.

Material Story

These eye-catching pen blanks are crafted from **Yellowheart**, one of the most vibrant and cheerful exotic hardwoods available. Renowned for its brilliant, natural lemon-yellow to golden-yellow color, Yellowheart stands out with a bold, sunny appearance that few other woods can match.

This dense hardwood features a straight to slightly interlocked grain with a fine, uniform texture that turns smoothly and finishes to a beautiful, lustrous polish. The striking color makes it perfect for creating bold, modern pens or adding a bright accent to segmented turning projects.

Each blank is carefully selected for rich, consistent color and quality, delivering excellent stability and outstanding visual impact in the finished piece.

About Yellowheart Wood

Yellowheart, also known as Pau Amarello or Brazilian Yellowheart, is a premium exotic hardwood native to the tropical rainforests of Brazil and parts of South America. Its scientific name is Euxylophora paraensis.

What makes Yellowheart truly special is its intense, natural yellow coloration — ranging from bright lemon yellow to deep golden hues. Unlike many woods that fade, Yellowheart holds its vibrant color remarkably well, though it can develop a slightly richer golden-orange tone over time with light exposure.

With good density and a Janka hardness rating of approximately 1,860 lbf, Yellowheart offers excellent durability while remaining workable for turners. It has a fine, even texture and machines cleanly, making it a favorite for decorative turning, pens, bowls, and musical instruments.

Yellowheart brings a rare burst of natural brightness and tropical energy to any woodworking project, creating finished pieces that are joyful, distinctive, and full of character.

Buckeye Burl Pen Blanks [Stabilized] - Premium American Figured Wood

Product Specifications

Blank Sizes: Each pen blank is a minimum of 5" long × 3/4" × 3/4" square.

Material: Genuine Buckeye Burl (Aesculus spp.) — Fully Stabilized with Cactus Juice.

Material Story

These stunning pen blanks are crafted from premium **Buckeye Burl**, one of the most colorful and intricately figured burls native to North America. Each piece displays wild, swirling grain with dramatic eyes, feathers, and bold color variations.

The blanks vary wildly in appearance — featuring vibrant grays, creamy blondes, rich oranges, reds, and deep purples. No two blanks are alike. Because raw Buckeye Burl is naturally unstable, we fully stabilize every blank using **Cactus Juice stabilizing resin**. This premium stabilization process locks in the beautiful figure, eliminates movement, increases density, and allows for smooth, clean turning with a high-gloss finish that beautifully highlights the intricate patterns.

The result is a stable, eye-catching blank that turns like a dream and produces show-stopping, one-of-a-kind pens.

About Buckeye Burl Wood

Buckeye Burl comes from the Buckeye tree (primarily Ohio Buckeye or California Buckeye). It is highly prized by woodturners for its exceptional figure and vibrant natural colors. The burl forms on the lower trunk and roots of the tree, creating dense clusters of dormant buds that result in complex, chaotic grain patterns.

When stabilized with Cactus Juice, Buckeye Burl becomes one of the most visually striking domestic burls available. The stabilization process not only strengthens the wood but also intensifies and preserves the stunning array of colors — often revealing bright pinks, oranges, yellows, grays, and blondes with contrasting dark streaks.

With excellent workability after stabilization, Buckeye Burl is a favorite for high-end pens, knife handles, bowls, and other decorative turnings. Its bold figure and color make it stand out in any collection.

Owning a stabilized Buckeye Burl blank means working with a true American natural wonder — a rare and beautiful piece of domestic burl that transforms into one-of-a-kind, conversation-starting finished pieces.

Embedded blanks with  Consolidated B-24 Liberator metal material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Consolidated B-24 Liberator, commonly known as the Liberator, is a cornerstone of U.S. Army Air Forces strategic bombing capabilities. Introduced in 1941, this subsonic, four-engine heavy bomber was designed for long-range missions, enabling it to strike distant targets with significant payloads. Powered by four Pratt & Whitney R-1830-65 Twin Wasp radial engines, each producing 1,200 horsepower, the B-24H can carry up to 8,800 pounds of bombs. Its range exceeds 2,100 nautical miles, making it a vital platform for operations across the European and Pacific theaters during World War II.

The B-24H’s versatility is achieved through its high-aspect-ratio Davis wing, robust airframe, and advanced defensive armament, including up to ten .50-caliber machine guns in turrets and waist positions, allowing for effective defense against enemy fighters. A notable component is the aluminum fuselage skin, which provides essential lightweight construction and structural durability. For instance, a section of fuselage skin from such an aircraft, salvaged after a combat loss over France in 1944, highlights the material’s critical role in enduring battle damage and environmental stresses. This skin was later repurposed, reflecting ongoing preservation efforts for historical aircraft parts.

With over 18,400 units built across all variants, the B-24 remains one of the most produced heavy bombers in history. Operated by units such as the 466th Bomb Group from bases like Attlebridge, England, it saw extensive combat in World War II, conducting strategic bombing raids over Germany, Ploesti oil fields, and Pacific targets, delivering critical strikes and supporting Allied campaigns.

These aluminum embedded blanks are crafted from Consolidated B-24H Liberator serial number 42-95203’s fuselage skin, salvaged following its combat loss. The material is certified and distributed by Hardin Penworks, LLC, and is guaranteed to be 100% authentic.

Sierra embedded blanks with Folland Gnat T.1 "Red Arrows" aluminum wing material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Folland Gnat T.1, commonly known as the Gnat Trainer, is a cornerstone of Royal Air Force advanced jet training capabilities. Introduced in 1959, this subsonic, swept-wing aircraft was designed for affordability and simplicity, enabling it to serve as an effective trainer for fast-jet pilots while being suitable for production in less industrialized nations. Powered by one Bristol Siddeley Orpheus 801 turbojet engine, producing 4,520 pounds of thrust, the Gnat T.1 can reach speeds up to 636 mph and has a range of approximately 500 nautical miles, extendable with external fuel tanks, making it versatile for training and aerobatic displays.

The Gnat T.1’s agility is achieved through its compact design, lightweight construction, and responsive controls, allowing for precise maneuvers and high performance in flight. A notable component is the aluminum wing, which provides essential structural integrity and aerodynamic efficiency. For instance, a wing from such an aircraft, replaced due to damage, highlights the material’s critical role in maintaining flight performance. This wing was later repurposed, reflecting ongoing preservation efforts for historical aircraft parts.

With 105 units built for the RAF out of a total 449 Gnats produced, the Gnat T.1 remains one of the most iconic training aircraft ever developed. Operated primarily by No. 4 Flying Training School at RAF Valley, Wales, it has been pivotal in pilot training and gained fame through its use by the Red Arrows aerobatic team from 1965 to 1979, performing in airshows across the globe with formations like the Diamond Nine.

These aluminum embedded blanks are crafted from a Folland Gnat T.1’s wing, replaced due to damage. The material is certified and distributed by Hardin Penworks, LLC, and is guaranteed to be 100% authentic.

Lambeau Field is an outdoor athletic stadium in the north central United States, located in Green Bay, Wisconsin. The home field of the Green Bay Packers of the National Football League (NFL), it opened in 1957 as City Stadium, replacing the original City Stadium at East High School as the Packers' home field. Informally known as New City Stadium for its first eight seasons, it was renamed in August 1965 in memory of Packers founder, player, and long-time head coach, Curly Lambeau, who had died two months earlier.

The stadium's street address has been 1265 Lombardi Avenue since August 1968, when Highland Avenue was renamed in honor of former head coach Vince Lombardi. It sits on a block bounded by Lombardi Avenue (north); Oneida Street (east); Stadium Drive and Valley View Road (south); and Ridge Road (west). The playing field at the stadium has a conventional north-south alignment, at an elevation of 640 feet (195 m) above sea level.

The stadium completed its latest renovation in the summer of 2013 with the addition of 7,000 seats high in the south end zone. About 5,400 of the new seating is general, while the remaining 1,600 seats are club or terrace suite seating.[17] With a capacity of 81,441, Lambeau Field is the fifth-largest stadium in the NFL with standing room, but is fourth in normal capacity. It is now the largest venue in the state, edging out Camp Randall Stadium (80,321) at the University of Wisconsin in Madison.

Lambeau Field is the oldest continually operating NFL stadium.[19] In 2007, the Packers completed their 51st season at Lambeau, breaking the all-time NFL record set by the Chicago Bears at Wrigley Field (1921-70). (While Soldier Field in Chicago is older, it was not the home of the Bears until 1971.) Only the Boston Red Sox at Fenway Park and the Chicago Cubs at Wrigley have longer active home-field tenures in American professional sports.

Sierra and Bolt embedded blanks with WWII German A-4 V-2 Ballistic Missile - "Vengeance Weapon 2" recovered relic material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The German V-2 rocket, officially known as Vergeltungswaffe 2 (Vengeance Weapon 2) or Aggregat 4 (A-4), was the world's first long-range guided ballistic missile. Developed during World War II under the direction of Wernher von Braun at the Peenemünde Army Research Center, it first launched successfully in October 1942 and entered operational use in September 1944. Standing 46 feet tall with a diameter of 5.4 feet and weighing 27,000 pounds at launch, the V-2 was powered by a liquid-propellant engine using alcohol and liquid oxygen, achieving speeds over 3,500 mph (Mach 5) and a range of up to 200 miles. It carried a 2,200-pound Amatol warhead, striking targets like London and Antwerp with supersonic speed, making interception impossible. Over 3,000 V-2s were launched, causing significant civilian casualties and terror. Post-war, captured V-2 technology influenced U.S. and Soviet rocket programs, contributing to advancements in rocketry. Nicknamed "Buzzbomb" by some, though more accurately associated with the V-1, the V-2 was the first human-made object to reach space in suborbital flight.

These pen blanks are crafted from authentic fragments of a V-2 rocket, preserving its wartime history. Suitable for historians, collectors, or military enthusiasts, they provide a connection to this missile's past through a functional writing instrument.

Relic History: The fragments originate from a V-2 rocket launched on March 2, 1945. These pieces document German rocketry efforts during the final stages of World War II, offering a tangible link to one of the weapons used in that period.

Sierra embedded blanks with Convair B-36 Peacemaker material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Convair B-36 Peacemaker, a massive strategic bomber, was the backbone of U.S. nuclear deterrence during the early Cold War. First flown on August 8, 1946, and entering service in 1948, it was the largest mass-produced piston-engine aircraft ever built. Powered by six Pratt & Whitney R-4360-53 Wasp Major radial engines and four General Electric J47 turbojets, it generated 40,800 horsepower, reaching 435 mph and a range of 10,000 miles. Its 230-foot wingspan and 162-foot length enabled it to carry 86,000 pounds of bombs, including nuclear payloads, at altitudes up to 48,000 feet. Designed for intercontinental missions without refueling, the B-36 served with the Strategic Air Command, embodying "peace through strength" until its retirement in 1959. Its size and complexity earned it the nickname "Big Stick."

These pen blanks are crafted from the authentic skin of B-36 Peacemaker, serial number 42-13571, preserving its monumental legacy. Perfect for historians, collectors, or aviation enthusiasts, they transform this Cold War giant into a unique writing instrument.

Serial Number 42-13571 History: Accepted in 1949 as a B-36A, 42-13571 was converted to a B-36B and later an RB-36E reconnaissance variant. Assigned to the 5th Strategic Reconnaissance Wing at Fairfield-Suisun (Travis) AFB, it was retired in 1957 to Fort Worth, Texas, and later scrapped, with parts preserved for posterity.

Sierra embedded blanks with North American T-28C Trojan material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The North American T-28C Trojan, a piston-engine military trainer, was a cornerstone of U.S. Navy pilot training in the post-World War II era. First flown in 1949 and entering service in 1950, it was designed to replace the T-6 Texan. Powered by a Wright R-1820-86 Cyclone engine producing 1,425 horsepower, the Trojan reached speeds of 343 mph and had a range of 1,060 miles. The T-28C variant, built for the Navy, featured a tailhook, shorter propeller, and reinforced structure for carrier landings, making it ideal for advanced training. Nearly 2,000 T-28s were produced, including 299 C models, training pilots in aerobatics, gunnery, and carrier operations. During the Vietnam War, some Trojans served in counter-insurgency roles. Its predictable handling and excellent visibility earned it the nickname “Pilot Maker.”

These pen blanks are crafted from the authentic fuselage skin of T-28C Trojan, Bureau Number 140597, preserving its legacy. Ideal for aviation enthusiasts, veterans, or collectors, they transform this trainer’s history into a unique writing instrument.

Bureau Number 140597 History: Accepted by the Navy in December 1956, BuNo 140597 served primarily with Training Squadrons Two (VT-2) and Three (VT-3) at NAS Whiting Field, Florida. In 1968, VT-3 set a record with 174 instructors and 162 T-28s, flying 110,000 instructional hours. Retired to the Military Aircraft Storage and Disposition Center in 1975, it was sold in 1982.

Sierra embedded blanks with McDonnell Douglas F-4B Phantom II material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The McDonnell Douglas F-4B Phantom II, a twin-engine, all-weather fighter-bomber, was a mainstay of U.S. naval aviation. First flown on May 27, 1958, and entering service in 1960, it was renowned for its versatility and power. Powered by two General Electric J79-GE-8 engines, each producing 17,000 pounds of thrust, it reached speeds of Mach 2.2 and had a range of 1,600 miles. Its 38-foot wingspan and armament, including AIM-7 Sparrow and AIM-9 Sidewinder missiles, plus up to 16,000 pounds of bombs, made it lethal in air-to-air and air-to-ground roles.
