The Pro-Tech Whiskers collaboration knife is based on Mike Allen’s fantastic bolster release mechanism. Upon first glance there is nothing about the BR-1 to make you suspect it’s an automatic knife (no button of course). The BOLSTER section of the handle slides up – this very deliberate movement is what fires the blade open and also unlocks it from the open position.
Pro-Tech has been producing some of the highest quality and snappiest automatic knives in the world since 1999. Family-owned and based out of Placentia, California. Each Pro-Tech Knife is warrantied to the original purchaser to be free from defects in materials and craftsmanship by Pro-Tech Knives, LLC for life.
