I reshaped my Fiskars pick / mattock using a couple of gold pans as templates today to reduce its overall weight. Beaute pick but It felt like i was cutting down a tree with a block buster. And was a pain to carry for long periods. Weight saving 340 grams or 10% of overall weight. Ive still got the anti vibration handle and swing ergonomics with faster acceleration and much higher impact speed.
So you took the sides in, sort of like a paraboloid? Nice!
