Heck, buy two. And whittle with both of 'em!
I have two Whittlers: one that a very generous forum member sent me, a Case Seahorse in
Tru-Sharp steel, and a Rough Rider locking Whittler that I bought last year - a copy of the Case/T. Bose design that I bought before I knew it was a copied design. I had a third, a small abalone-handled Rough Rider swell-center Whittler, but I sold it at a garage sale because it was just too small to carve with.
We just moved into a house with a garage, so I have a shop now, so I've been whittling a lot more, mostly with the Case, less with the RR. The Case has held up pretty well. My preference is for carbon steel blades, but the
Tru-Sharp is getting the job done. I'm not into blade etches, other than maker's marks, so if the etch wears off, I'm not going to worry about it.
I have a H&R (Hen & Rooster brand) six-blade Congress, with one set of blades sharpened to a more course edge, the other set sharpened to a fine edge. When I was eleven or twelve years old, an old neighbor advised me that if I was serious about carving/whittling, then have a knife with two or more blades: a "rough" blade for "hogging off" (removing a lot of material) and a "fine" blade for more detailed work. Start with the rough, finish with the fine. He could carve anything - out of anything - including carving your name around a peeled chestnut. I haven't worked enough with my H&R to know how well that works. It'll get more work time during the coming winter.
I doubt I'll ever get even close to that kind of ability.
As I said above, I also have the RR locking Whittler. So far the stainless steel has held up pretty well, but it does get sharpened a little more often than the Case. I don't really need the lock on this one; I haven't learned any techniques where I'd need the safety of a lock.
Hope that's informative; I'd be interested to see what this thread produces, and hopefully folks will post pics. (Of their work, that is.)
