The Victorinox (formerly Forschner*) 7 inch Straight, Flexible Blade Fillet Knife by Victorinox features a Fibrox handle and extremely sharp blade that holds its edge. The patented Fibrox handle is dishwasher safe and slip resistant, even when wet. It is also NSF approved, as crevices that would offer hospitality to bacteria are minimized. As with all R.H. Forschner knives, the handle is ergonomically designed to minimize wrist tension and provides a natural fit.
