Schrade's ST5E Tough Tool was the first plier multitool with adjustable slip jaws. (Spyderco's
SpydeRench employed this feature earlier, but in a less conventional tool) The slip jaw allows the pliers to get a grip on larger objects such as pipe or bolt heads. However, the jaw and handle arrangement of the ST5E make it one of the largest most inconvenient-to-carry multitools ever. The slip jaw also makes the tool annoyingly difficult to fold up at times.
Jaws
Jaw construction on the ST5E is made up of laminated plates of steel, riveted together.
Note that the laminations allow one jaw to pass directly
through the other jaw, making for an incredibly strong pivot.
The ST5E is unique in its ability to adjust to two different size jaw openings. (see photos at bottom of page)
Jaw serrations are very sharp and aggressive. Bypass wire cutters are blunt, and appear to be intended for hard wire.
Handles/Frame
Handles are bent in a complex shape, forming a complete rectangular tube at one point.
All pivot points are rivets, not screws.
Finish is matte bead blast stainless all over.
The SCHRADE TOUGH logo is stamped in one handle, patent info in the other. No inch or metric scales are present.
