The CS tantos should be fine for collecting, but don't try stabbing one into any hard material.
There was a post once by a guy who severly injured his hand while stabbing something - I can remember what - with a CS tanto. The guard was too short to stop his hand from sliding onto the blade.
Guards are a controversial subject. Some people want little or no guard on a knife because it gets in the way of making certain cuts. However, I'll bet that guy who cut himself with the CS tanto loves long guards now. I prefer them too, having cut myself with knives having slippery handles and short, rounded guards.
