Last week I was excited to have delivered to my office Delta2Alpha’s premier folding blade, the H2 Sierra. My first impression after unpacking it was this: this is an impressive, serious blade. What I mean is that you can just tell this knife was made by serious people, for serious people. It is not some “just good enough” type of thing you’d find in your standard megastore. It’s not even the kind of thing you’d find in your standard sporting-goods or outdoors store.
