I'm glad the Spydiechef exists because I always hear complaining about "wanting a thinner knife", even from people that have knives like the Delica (which is already thinner than it used to be). I mean, I don't want thick stock like a Tops knife usually, but if you want extremely thin from a design thats already out, like the delica, then beg for a different and similar knife, because most people like it how it is. Or if you want super thin and slicey get a traditional or a food knife like a pearing knife or something.
Personally I'm thrilled the Shaman was made just like it is. Its very slicey and yet robust enough when you use a beefier knife. The flat grind was a good choice. Not every knife needs to be razor blade thin to cut well. This one, especially with the compression lock, makes it kinda close to a fixie that you can clip to your pocket. I feel the shaman really filled a gap in spydercos lineup and I'm excited to see it and hope it sticks around.
The spydiechef is really popular and rightfully so. Nice lines, makes me think of a chefs knife while still being pocketable and handy for EDC tasks.
I want both to stick around, and I hope not to see changes beyond aesthetics.
