I have a couple of them and I love em, but they definitely don't wear like a German knife. It's noticably sharper than our sharpest German knife, but over time they've developed a series of small nicks along the blade. These are still our go-to knives, but when we're cutting something particularly tough where we want to put one hand on top of the blade, we pull out the German knives. The blade is thicker so you can comfortably put a hand on the back... so these knives are not a do-anything knife and you need to be ok with the inevitable chips.

Unless you already have experience with throwing pottery on a wheel, I wouldn't recommend getting that. I thought I'd love it, but I found it really physically uncomfortable to use the wheel. I still love making pottery, I just do it by hand, no wheel needed. If you haven't set up a pottery studio at home, there's a long list of non-wheel stuff that would be good for that.
