A cinch to open, closes only when you want it to. The SlipTron is a knife you can trust. Featuring our patented slip-joint design, which locks the blade into an ultra-secure position while open, youÂ’ll never have to worry about accidental closure again. The entire construction is stainless steel – from handle to blade – so you know youÂ’re set when it comes to durability too. As safe as it is sharp, the SlipTron is a tool you can carry with confidence.
