Patent number: 10836028Abstract: Presented here are toollessly releasable, interchangeable handles for hand tools and methods of use thereof. Hand tool users often experience discomfort and injury because hand tool handles are not well suited to each user's hands. In addition, different hand tools have different handles, so users that switch between hand tools often find a different level of comfort with different hand tools. The disclosed platform for interchangeable handles for hand tools allows a user to attach handles custom fitted to their hand to any corresponding hand tool, and likewise allows different users to share a hand tool by detaching the first user's handles and then attaching a second user's handles. Various embodiments for connecting interchangeable handles to hand tools are shown. Additionally, a fluid reservoir disposed within an interchangeable handle and locking mechanisms for keeping the interchangeable handles attached to the hand tool are disclosed.Type: GrantFiled: June 15, 2017Date of Patent: November 17, 2020Assignee: HERBAVORE LLCInventor: Robert Saito

Patent number: 4630368Abstract: A flush cut handsaw has a generally planar handle oriented in a plane perpendicular to and parallel to the saw blade axis, or saw tooth edge, and on one side of the blade so that the saw may be manually used in a conventional sawing mode with the saw blade riding on and parallel with the floor surface. The saw is particularly useful in cutting off plastic plumbing pipes flush with the floor surface and in other circumstances where a smooth, even cut without slant or skew is required.Type: GrantFiled: March 11, 1985Date of Patent: December 23, 1986Assignee: Plastic Oddities, Inc.Inventor: Lewis B.
