I upgraded my lime slicer with a stump, changed the size and strengthened ribs. Ergonomic holder. Do 2 at a time. I made the knife from scrap stainless 10 years ago on my torchmate plasma i built here in Peru. I have given away at least a hundred to the natives over the years and this one, with handle made from scratch, still serves me well. I do suggest you make the slicer in petg and it is a gift to your favorite bartender or Latin dama.
