a ripper

A tool for wood

Rapid drill stabilized by two columns adjustable on a support, it allows to realize, among others, impeccable profiles. It becomes indispensable for all those who work with wood.

An American invention

In 1912, Oscar Onsrud opened a tool shop in Chicago. Imaginatively, he designs a compressed air motor that must, initially, allow to supply independently the lighting of the steam locomotives. His son Rudy takes the principle to quickly turn a milling cutter on a portable device, then it multiplies the forms of strawberries to obtain various profiles.
The success is such that the firm Onsrud, founded in 1920 and now integrated into the LMT group, continues to be one of the jewels of carpentry tools. Although other devices developed in 1905 by the Kelley Electric Machine Co. in Buffalo, all were abandoned in the 1930s in favor of the ripper, quickly adopted in the United States and Europe.

An improved tool in Germany

In the 1960s, the tool is improved in Germany by the engineers of the firm ELU (now DeWalt, in the Black & Decker group) and takes the form we know it (two handles, two columns, three stops, guiding devices).

An always useful utility

Since then, the main advances have been in safety, the precision of the cuts (playing on the shapes, the materials of the cutters and the variations of speed) and the handling of the tool.
