Greg Holt, host of Scuba Radio captured me swimming with Sperm Force fins in Grand Cayman Islands. You just glide along like a sea snake. No effort at all to move quickly. Like cracking a whip.

It's been over 28 years since Jimmy Gray passed on. We worked side by side for over 10 years with Force Fins. Hard to imagine he is gone, I learned so much about shaping and fiberglass tooling. Jimmy was laying up Kirby Morgan Diving hats and brought years of surf board shaping to the table....I also learned from our Artist Father Gordon B. Evans.

Molds are generally cut out of a big block of steel. At the time we started Force Fin, each mold had around a $40,000 price tag. In today’s dollars that is the equivalent of around $120,000. Bob Evans hand shaped master tooling, with blades propotional to foot for sizes xs, small, medium, medium large, large, extra large, 2-X Large. Over the years we made more than 30 models of Force Fins. To launch with a size run just for the Original and Pro Model Force Fins we were were looking at a cost of more than $750,000 current dollars, with that investment capital tied up for around 18 months. That’s a pretty high capital expense for a fin company.

Never one to cower at a challenge, Bob Evans decided to find a solution. He applied techniques he learned from his artist/sculpter father and growing up as a member of Hermosa Beach California surfing community to develop fiberglass epoxy (later filled with aluminum) tooling and molds. Each mold came in with a cost of around $3,000, and Force Fin was up and running – successfully!

Over the year, Bob Evans and his crew made 100’s of molds, that together produced millions of Force Fins. Dr. Phil Nuytten with his signed Force Fin mold. Well own American History 40 years now, Collectible – Revolutionary Mold 712 for Revolutionary Force Fin – Force Fin

Aren't you a bit gloomy on that one ? I'd have said an archaeology dig...
