I have a few, and I've rehandled they're cheap knives often, as I found they are a good source for cheap stainless blades. For rehandleing, I only use an old type with a cheap plastic handle. And I don't buy the sheath with it. But the better muela knives have really good sheaths. I only buy the cheap ones since I only need the blade.
Muela knives are generally good quality knives, but since this is a big knife-company, they also produce less good knives.
I suspect you are looking at a better one.
If it says inox, and mo(lybdenum) and va(nadium) you have a stainless blade, an upgrade from 420 steel, defenitly tougher and a better edgeholder, but most of all, easier to sharpen. And you will resharpen it often, as it is a bad edgeholder compared to 52100 or CPM 440 V. But for the money....it is a good deal. But a sharpening steel with it and keep that with it, and you'll be O.K.
personally, I would but the sharpening steel too, but for a user I would get myself a coldsteel bushman.
