Slipjoint Knife

While researching videos the other day I came across the term “slipjoint” in reference to pocket knives. The Wikipedia article states that the slipjoint style pocket knife is “one of the most ubiquitous” types of pocket knife utilizing a “strong backspring” to lock the blade in place. Often thought of as slotting in between fully mechanical locking, and non locking knives. The slipjoint knife has many variations each with a unique name and take on the slipjoint style: Peanut, Barlow, Sunfish or Elephant’s Toenail, Congress, Sowbelly or Stockman knife, Canoe, and Trapper.

The written description of a slipjoint knife is all well and good, but I felt I needed more, so back to Google I trekked and from the land of YouTube I brought back this video by knifesketch101 explaining slipjoint knives and their “appeal”.

The video helps identify and explain the appeal and identifying features, however I was left wanting to know more specifically about the slipjoint mechanics. Thanks to Hydra572HQ for this pretty awesome (by YouTube standards) video on slipjoints complete with hand-drawn explanations! 1:45 is the money shot, in case you don’t feel like sitting through all 5:14 seconds.
