Monday I was asked, "What's the difference between an industrial straight trimmer and a bent trimmer." The only difference is the placement of the center of the handle in relation to the blade.
The benefit of the bent trimmer over the straight is it's better for cutting on a table. The customer doesn't have to hike the material up as much to make a cut, so it makes it easier to cut a straight line. Wolff sells far more bent trimmers than straights. Most of our straight trimmers are sold to the poultry industry for trimming fat.
