A kitchen instrument with a replaceable head is described having a handle, an ejection shaft, and an ejection knob. The handle is mostly hollow with an opening on a first side and an opening on the second side opposite the first side. The opening on the first side includes an indent shaped to secure a replaceable head by preventing exiting from the indent and also from rotating. The replaceable head has a connector with a first connecting portion and a second connecting portion shaped to be secured in the indent. An ejection shaft is sized and arranged to be inserted in the second side and pass through the handle. The ejection shaft is sized to press on the replaceable head to eject the replaceable head. Multiple replaceable kitchen utensils in the form of replaceable heads are attachable to the same handle of the kitchen instrument.

The present invention is for a handle system for a woodworking tool to allow both the safe stowage of a woodworking tool and the operational use of the woodworking tool. A handle configured with a first collet receiver and a second collet receiver interconnected at either end of a generally hollow longitudinal handle. The collet receivers are adapted for receiving and interconnecting with a collet, and the collet is configured to receive and hold a woodworking tool therein. The first collet receiver enables the stowage of the woodturning tool within the longitudinal handle, and the second collet receiver enables the use of the woodturning tool in a working configuration which constrains the woodturning tool extending axially away from the longitudinal handle.
