What Tom said, but different. Got MY ALL TIME GRAIL knife Monday.

Tried for 4 or 5 years. Couldn’t find one for sale any where. Finally figured out how to contact the designer and sent him an e-mail explaining my quest. He e-mailed me back saying he might be able to help me and asked for my snail mail address. Well I thought, right I will probably never hear from him, or at best a contact for getting one of the knives. About a month (I think) later I got a package from him with both the trainer and live blade inside! It is like he took a measure of my hand when he designed them. I am still in cloud 9.


This one just shows how you can maintain possession of the knife in different situations and doing different tasks along with an explanation of the knife. The pics will advance on their own.
