I've been kind of tuned into RealSteel Knives for a while now and so far haven't been disappointed. I've long been a proponent of their H6 Blue Sheep as an alternative to an Ontario RAT 1 or an ESEE Avispa. I hope to some day post a comparison review of those three knives because I honestly feel the H6 wins. Just yesterday I received the H6-S1 which is a slightly smaller version of the H6 but with a framelock rather than a liner lock. I've been really impressed with it initially and encourage others to check one out.
A couple of other RSK's that I have are basically slightly modified copies of existing SanRenMu designs...the E963, E77 and the E79...nothing special but solid beater knives.
I even spurged on one of the high dollar RSK's, the S-Series Stinger in gold. It's a pretty decent knife but certainly not worth anywhere near MSRP...it's a $100-150 knife, which is about what I paid for mine. If you're familiar with Kizer knives, I'd put it right around that level of quality. Certainly on par with the bulk of Spydercos that come out of Taiwan.
My problem is finding the knives for sale at anything less than MSRP. Have any of you found a US retailer who offers the knives for sensible prices? $65 for an H6 Blue Sheep destroys its value advantage against the RAT 1 or Avispa.
