I thought this would be of interest given several threads on AMTAC blades.

Frank Windle died of COVID recently. He will be missed. I met him at a Force on Force class a couple of years ago. I believe he was brought in to be the tough guy for the class, and he played the part well. He loved knife training, fighting, and he was a tough guy. I took a shooting course in Bangor at his home range in September and was shocked that he wasn't there. He passed the following week.

He was the inspiration behind the AMTAC Northman and made the prototype. Bill Rapier and Kyle Defoor have social media posts about Frank.
