The slipjoint is an archetypal knife design rooted firmly in the past. Estimates place the earliest slipjoint design to have originated sometime in the 1600s. There are so many ways to pay homage to the glory days of knifemaking, but to modernize the design and create a resolute and bulletproof everyday carry knife takes a knifemaker like Jim Burke. Simplicity remains paramount for a modern slipjoint and Burke has built this knife with quality materials and little fuss or aggrandizement. The result is a gentleman’s pocket knife with the DNA of your grandfather’s knife and the aesthetics of a modern master craftsman.

This Triple Aught Design edition slipjoint from Jim Burke is a 1 of 1 limited edition.

  • Chad Nichols stainless damascus blade with hand rubbed satin flats. Traditional drop point blade profile with a half swedge and nail neck.
  • Robust action on the slipjoint spring ensures concerted pressure is necessary to close the blade. Two position detent further aids safe opening and closing.
  • The ergonomics of handle are perfect for everyday carry and use for all but the heaviest work. The drop butt handle creates control, and the extensive chamfering reduces the grip’s bite.
  • The titanium frame features our signature three fullers and a blind mounted 3D satin titanium pocket clip.
Behind the Scenes with Burke Knives

Dissatisfied with what the market offered to law enforcement personnel, Jim Burke, himself a member, worked with his father to build a liner locking folder together. Without any outside help, the duo used magazine photos to build a series of prototypes and the first Burke Knives design was born in 1994. As Burke’s profession continued to evolve from Fugitive Apprehension, SWAT, Narcotics Raid Team to Security Contracting and Personal Protection, so did his knives. Using first hand field knowledge, Burke Knives delivers high quality custom tools for soldiers and civilians that will save your life or sit beautifully amongst a collection.
