>>1408057It is more questioning what you'll be doing with it and making sure we are on the same page than actual advice. The more info known, the better a recommendation can be.
Those hardwoods are the only thing I carve on around here. The harder the wood the faster it will dull the blade. Which is why people love balsa wood carving. Since you already have a knife for detail carving, dislike jimping, need something with a fixed blade under 4", I recommend searching for a, "fat knife." Those are all the design you are looking for, but keep in mind that getting the specific style and thickness you want may be difficult. you may need to buy a custom made one, if you can't find a commercial one, or are unable to make your own. Here's some examples:
3.175mm = 0.125" = 1/8" thick, fyi:
Boker Plus BOB (a bit thick at 0.28")
AD Fat Fish-1 (custom only, at 0.140" thick)

There are many others, but most have jimping or a retarded hole in the blade. Thoug, tht hole in the blade is meant to be a grip.
