I made this knife on command for Lars 40th birthday.
Specifications were high carbon damascus blade 7cm long and 9cm handle, no spring, no lock.
I realized later that I liked this little knife because it reminds me of the way a Teckel walks, kind of hopping like there is something wrong with a hind leg.
I make it also with plain carbon blade with 1,2% Carbon. (Øberg file steel from Sweden).
It is very nice to have it in a purse or in a pocket, until you need it to cut something, or just to hold it in your hand.
