I have two, and they are marked differently from each other. One is marked only Stainless Steel on one side, and has no marking on the reverse side. The second Sea Hawk has Stainless Steel Japan (with the logo upside down from the other one) and the Aqua Lung logo on the reverse side.
Were Sea Hawk knives ever made in the US? I ask because pretty much every Japanese made knife I've ever owned has had Japan stamped on the blade. I love Japanese made knives, so am not discriminating, merely trying to learn as much about these knives as possible.
I won't dive the made in Japan knife because she's basically new in box. The other one has significant weathering already so I don't feel bad adding more wear marks.
Pictures are below. I apologize for not using pics I've taken myself, but the seller's pictures were better than my phone camera. I can take more pics with my phone tomorrow.
Here's the non-Japan marked knife


And here's the Japan marked blade
