Rob Cosman's IBC Bench Chisel - 5/8 inch
Determined to design a better chisel, IBC and I teamed up and developed what I consider to be the best woodworking bench chisel on the market today.
These chisels meet all five criteria of a great chisel: comfortable, good steel, properly shaped, easy to set up, and the ability to change handles.
The quality, craftsmanship, and metallurgy on these "made in Canada" chisels are second to none (see product details tab for specifics).
The steel holds an edge beautifully
The back sits flat, meaning very little work is required to progress through the grits to obtain a mirrored finish.
Each chisel is perfectly balanced, fits comfortable in your hand, and feels great.
The blade tang extends through a hardened steel ferrule and into a threaded hardened steel core that is inserted through the center of the wood handle and is securely attached to an aluminum striking cap.
When the handle is detached, the blade can be separated from the ferrule to lay perfectly flat on a surface for flattening or sharpening.
- Size: Bench Chisel Handle total length: 3.87” Bench Chisel total length: 9.2”. Bench chisel blade length including the tang is 6“.
- Blade: Made from AISI High Vanadium A2 tool steel fully stress relieved, triple tempered, cryogenically treated and hardened to 60-62 HRC. Back sides have a semi-mirror finish. Beveled sides are ground with a small 90° flat for comfort and safety during use. Cutting edges are ground with a primary bevel @ 30° for the lower sizes up to 3/8” and @ 25° for the larger sizes up to 1”. All cutting edges are ground square to the two side flats, with a 2° higher micro bevel and ship sharp enough from our factory to cut the hair on your arm.
- Handle Hardened Steel Core: Made from a 3.00” long x 3/8” round stress and fatigue resistant steel bar and hardened to 54-56 HRC with a double temper for strength and durability. Its finely tapped ends attach to the threaded blade tang and striking cap precisely and securely to make these chisels extremely rigid. It is also hollowed and milled open in its mid section for balance and weight. At less than 20 grams, it still has more than enough tensile strength to easily seal the chisel together indefinitely or, repeatedly.
- Handle Striking Cap: Made from a solid round aluminum bar, it has a precision turned domed top and a finely threaded center post that is precisely and securely attached to the hardened steel core. Its wide flat back seats flush and firm against the matching flat on the back of the wood for a wide area of contact. Tightening the handle compresses the back cap against the wood, fixing both firmly in place. Hand polished on domed surface. Weight: 10 grams.
Handle Wood: IBC Chisel handles are currently available with Maple or Walnut wood. Each wood is 3 1/2” long, center bored to fit its steel core and cut flat on top and bottom for a wide area of contact with the hardened ferrule the aluminum back cap. Tightening the chisel compresses the wood between them to seal it in place. When the handle is detached, the wood can be separated from the steel core and back cap to customize the handle with your own wood species and / or profile.
