Cosmanized IBC Chisel: 1/8 inch
We think our IBC chisels, that Rob and IBC jointly developed, are the best woodworking bench chisel on the market today. There is just one small problem, IBC does not make the chisel in an 1/8 inch size. Since many of our customers have requested a 1/8 inch chisel, we decided to "Cosmanize" a 1/4 inch IBC chisel into a 1/8.
Working with our machinist we developed a grinding jig that precisely grinds out the 1/8 size while maintaining the relief angle and the all important flat area on the edge (guaranteed to be within 0.005” of 1/8 inch).
These chisels take a lot of time and effort to produce, so if we are out of stock just keep checking back for when we get our next batch.
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.
- Ferrule: Made from a solid round stress and fatigue resistant steel bar hardened to 54-56 HRC with a double temper for added strength. Center bored, reamed, and flat on the top and bottom to slip over the tang and seat flush and firm against the flats on the blades two shoulders at one end and the flat top of the wood at the other. This ferrule design and solid construction protects the blade tang, bolsters the wood and provides the chisel with tremendous strength to withstand the lateral stresses from prying. Hand polished.
- 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.
This is a welcomed addition to my IBC Chisel collection. The machining is flawless and the smaller size will allow me to get into those tight corners. Thanks for making great hand tools available to us.
Awesome product! The Cosmanized IBC 1/8 inch chisel is everything I expected it to be. It gets me into those tight frustrating joints like no other chisel. As usual, quality, ease of use, and effectiveness is a bar set high by Rob's products. Much Appreciated!
I have only used my new 1/8 " chisel a few times but it works great in hard to reach places.
Love the chisel. Comes flat with little effort to polish the back. Beware, very easy to skew. Works great for getting into tight spaces. One of my favs. Thanks guys
Love the IBC chisels and have been wanting a 1/8" for a long time! Grind is great and it's the great IBC steel that I've come to know and love. Have to be a little careful about not jamming my thumb between the shoulder of the grind and what I'm working into but that's a small adjustment.
