For some reason, SanRenMu's seem to evoke strong reactions in a lot of folks. I'm sort of puzzled, for two reasons:
1) the SanRenMu 710 is NOTHING even CLOSE to a sebenza. It's not a knockoff or a copy. It's clearly INSPIRED by the sebenza, but the size, fit'n'finish, and materials are different. I always thought imitation was the sincerest form of flattery. I would feel differently about this if actual technology or processes were stolen in the making of the knife, which clearly is not the case.
2) People are freaking out about the SanRenMu, but don't seem to be bothered with Springfield XD versions of Glocks, Armscor versions of 1911s, Taurus copies of S&W revolvers. What's the difference?
For what it's worth, I just last week bought two SanRenMu's, a 710 and a 962 (the one with a Spyderco hole and Axis lock). They're very good knives, for the price. I paid less than $10 each, including shipping. They're on par with similar low price chinese knives that are imported under well-known brand names. Specifically, these knives seemed identical in quality, fit, and finish to some Byrd Cara-Caras that I've handled. This makes sense, because a Byrd knife that retails for $20 probably cost the dealer $10, and the importer probably paid the factory $6 for the same knife. By buying a SanRenMu, you're bypassing the middlemen and paying ~$7 plus shipping, and saving the $10 yourself.
As I said, the fit and finish a very good, and the blade steel is good quality, but obviously less than "super steel" like VG10 or similar. I bought mine to check out what all the hubbub was about. I'll most likely use them for another week or two, sharpen them up, and give them away to non-knifepeople.
SanRenMu's are fun to buy, and the value is there, so I recommend buying some to check out. In the long run, though, the other posters are right--buy quality. You won't regret it. When I give my SanRenMu's away, I'm going back to my Browning Ice Storm in VG-10.
