Wanted to see if anyone has experience with the Hawkbill?

I want to replace my 5.11/Bladetech Sidekick, which it looks like they stopped making (and mine is old, one of the earlier ones that was made in China, and the blade's seen better days).

those look cool. I love Hogue and have like 4 differnet models. The build qaulity and performace is awesome. only thing that would concern me is how do you sharpen those?
