Abstract
The present invention surrounds a handle system configured to receive a woodworking tool intended for use in woodturning operations. A blade is constrained between two removable handle sides, with the sides being removably interconnected using magnets wherein the handle sides adapted for being separated without the need for tools. The handle system includes the ability to use a double-ended scraper blade allowing a user to configure the blade to use a first cutting edge, or a second cutting edge as desired.
Claims20
A handle system for woodturning tools comprising:
- a handle comprising a first side comprising an internal aspect, and a second side comprising an internal aspect, wherein the internal aspects of the first side and second side are removably interconnectable;
- the handle further comprising a cavity extending in a longitudinal direction from a leading end of the handle toward a trailing end of the handle disposed between sides of the handle;
- a blade comprising a first end with a cutting edge, and a second end with a cutting edge, and the blade further comprising at least a first aperture through a thickness of the blade located between the ends of the blade;
- a locator pin configured to interconnect to the first side of the handle;
- wherein, when interconnected with the first side of the handle, the locator pin extends away from the internal aspect of the first side of the handle,
- wherein, when interconnected with the first side of the handle, the locator pin is configured to extend into the cavity when the first side of the handle is interconnected with the second side of the handle,
- wherein a profile of the first aperture matches a profile of the locator pin in at least the longitudinal direction, and
- wherein aligning the locator pin with the first aperture of the blade, and aligning the blade within the cavity when the first side is interconnected with the second side, results in constraint of the blade within the cavity in the longitudinal direction.

A handle system for woodturning tools comprising:
- a handle comprising a first side and a second side;
- the sides of the handle configured are wherein interconnecting the sides results in a cavity, extending in a longitudinal direction from a leading end of the handle toward a trailing end of the handle, disposed between sides of the handle configured to receive a blade therein;
- the first side and the second side interconnecting with magnets;
- the first side further comprising locator pin extending into the cavity from an inner aspect of the first side;
- the blade comprising a cutting edge on a first end, and a cutting edge at a second end;
- the blade further comprising a first aperture offset a first distance from a centerline of the blade, wherein when the first end of the blade is inserted within the handle in a first configuration, the first aperture of the blade is configured to align with a locator pin, wherein a profile of the first aperture matches a profile of the locator pin in at least the longitudinal direction;
- the blade further comprising a second aperture offset a second distance from centerline of the blade, wherein when the second end of the blade is inserted within the handle in a second configuration, the second aperture of the blade is configured to align with the locator pin, wherein a profile of the second aperture matches the profile of the locator pin in at least the longitudinal direction;
- and
- wherein aligning the locator pin with the first aperture, and interconnecting the first side with the second side constrains the blade in the longitudinal direction in a first configuration, and
- wherein aligning the locator pin with the second aperture, and interconnecting the first side with the second side constrains the blade in the longitudinal direction in a second configuration, and
- wherein removal of the first side from the second side results in the blade being unconstrained and allows the blade to be removed from the handle.
