ST1 Tough Tool

Schrade Tough Tool ST1.jpg The mighty Schrade Cutlery company, one of the largest knifemaking companies in America at the time, was late getting into the burgeoning multitool market. First produced 14 years after the Leatherman PST, Schrade's ST1 Tough Tool introduced a number of unique concepts, including side-folding blades and a new locking mechanism. Larger in size than the majority of competitive multitools at the time, the ST1 found favor with industrial workers and building trades professionals.

Jaw construction evolved over the years. See VARIATIONS below.

Profile is an unusual stepped needlenose. Fine and coarse serrations are included, along with a bypass wire cutter. No hard wire notch.


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.

Blades and Tools

A hole in one handle is provided for lanyard attachment.

Over the years the ST1 continued to evolve as manufacturing methods changed. Most dramatic differences can be seen in the plier head (see pictures at right) and the blade selection.


Introduced in 1997. Produced in USA until Schrade closed its doors in 2004.

A newer version, similar in appearance but lower in quality, currently produced in China and sold by Taylor Brands Schrade.
The ST5E Tough Tool and the ST2 Tough Chip bear a family resemblence to the ST1.

The famous Blackie Collins first patented the idea of side folding blades on a multitool. His patent #5062173 is a crude but obvious predecessor to the ST1:
The first patent registered in Schrade's name for the ST1 is this one #5963999
