I've had many requests for one of these over the years. I finally broke down and made two, one of which is on my own keychain! The other one (the nicer of the two) is offered here for sale. This piece is the regular 3 inch size and is made of Hakkapelitta Swedish Damasteel. I have given it a long 1 hour acid etch to really bring out the layers and create a deeply textured surface. This is a gorgeous tool and will be the only one available as I have used up my piece of steel.
