My grail is a pre-Benchmade Lone Wolf T1 with a rosewood handle. It's not the most unattainable grail, but it is a frustrating grail. They come up on ebay from time to time, but the price always ends up climbing over whatever I feel I can justify, even though that upper limit keeps climbing. When they were being made they were a hell of a bargain, but now they are selling for multiples of their original price.
I know the designer, Bill Harsey, and I really like his designs, but anything custom by him would be way out of my price range. Plus Bill usually designs for military applications, and I am not military (I'm an archaeologist, slightly different needs). So most of his knife designs are something I can appreciate, but have no real use for. Even with his Lone Wolf designs the T3` was way too big for my purposes, and since I have a Gerber Applegate Fairbairn Covert (also a Harsey design) I really don't need a T2 (though a T2 would be nice, especially with a micarta handle).
One of my favorite things about the T1 is that it is a tip down carry, because I like to carry in my back pocket. However after my most recent trip into the field I realized that a lot of the pants/shorts I wear in the field have flaps on the back, so I started thinking that maybe I should try getting used to front pocket carry. Harsey also designed the Fantoni HB01 and HB02. Those are very similar to the Lone Wolf T-series, except they are tip up carry.
So I broke down and just purchased a Fantoni HB02. I am still waiting for it to arrive. I decided that if I was going to pay the same price for a T1 as I would for an HB02 I might as well just get the HB02, since I think it is a slightly better knife (even though it is tip up carry).
But I still want a T1. Someday I will get my mitts on one.
