Abstract: A chef's knife with a weight-adjustable handle may have a cutting component and a handle, the handle having an end cap and an internal handle assembly. The internal handle assembly may be located in a cavity defined by the outer housing and may include a tubular member and at least one weight connected thereto. The at least one weight may be movable within the handle and/or adjustable in magnitude by removal from the handle after opening of the closure portion and removal of the internal handle assembly. The weight and/or weight distribution of the handle and the knife may therefore be adjusted. To cut with the forward portion of the blade, the weight may be moved forward. To cut with the rear portion of the blade, the weight may be moved rearward. The knife may also be converted from a lightweight knife to a heavy style knife and vice versa.

Abstract: A double-sided cutting board prevents mixing of flavors and cross-contamination, comprising a first flat board made of material selected form the group consisting of wood and bamboo and forming a first working surface designated for cutting one type of food, a second flat board made of plastic and forming a second working surface for cutting a second type of food, the first working surface and the second working surface lying in parallel planes, the first flat board and the second flat board held in fixed and spaced relation to one another by a rigid rim that extends around an outer surface of the cutting board. The plastic board may be for cutting fish and meat whereas the bamboo board can be used for cutting vegetables. When one wants to sharpen the knife blades, the bamboo board can be used such as for cutting meat.
