I used whatever I had, SAK, Buck 301, even a Buck 110, in the woods. At home - a Rick Butz 'chip carver' style was tried years ago - a smallish Wharncliffe style with a 'real' handle. I found some at a good price at a woodcarvers' show - bought several. Easier on my hand-grip, as my CTS problems manifested. My favorite now, with which I can actually still do some detail work with, is a Bark River 'T.U.S.K.'. I need a 'mini' or 'micro' version.
I bought a few Boker Tree Brand slippies last year. Good hand fit - recalled my Dad's whittling. Sadly, the first time I tried one last year, while feathering, and I pulled the blade back - without wiggling to insure it was free - it started to close. No blood loss - that time - recalled many a time I nicked myself, especially with 'dull' SAKs. That remind me of why my 20+ year older 301 was my last previous slippie purchase. I prefer fb's for whittling - lockback folders are solid second - along with the B-M AXIS lock - shocking what a B-M 710 - or 615 - can do! My wrist & hand are too old these days for slippies, it seems.
