Arguably the most important feature of the ST300; the pliers have been optimized for strength. To maintain the balance of materials when making room for the new removable wire cutters, more steel was added to key areas, making them the strongest, beefiest pilers we've ever produced. In addition the neck of the pliers is sloped for reaching even further into tight spaces.

Cutting wire regular, stranded, or hard is a common application on the job. When frequent, heavy pressure is applied, cutters can become dented and dull, causing the pliers to stick and jam up. By making the regular/hard-wire cutters removable they can be sharpened or replaced on the spot (replacement cutters sold separately). In addition, by optimizing the heat treatment process and replacing the standard stainless steel with premium 154CM the wire cutters will hold an edge three times as long for maximum durability.

The idea of clumping was originally introduced with the first Super Tool. By pulling on only one tool, you would get them all from the handle at once, including the knives. To improve on safety, the new ST300 has just that, Edge-safety Clumping�. If you pull on either of the two knifes they are the only implement that will come out. Conversely if you pull on any of the other features the sharp-edged ones stay put.

The ST300 straight blade is hollow ground for easy sharpening. Screwdrivers are in the sizes professionals use most and are also hollow ground for a better fit. The handles are rounded for comfort and have cut outs on the side to easily access blades when wearing bulky work gloves. The locks on the ST300 have been strengthened to ensure full engagement when the features are under heavy use.
