Why is it that about the time your favorite tool reaches the perfect length, it's too short? Fact is, most tools are thrown out long before they are worn out. In addition, tools are easiest to use when the blade is just long enough to get the job done. Hosaluk™ Handle Inserts let you enjoy the look and feel of traditional wood handles while allowing you to adjust the blade length to suit your needs. This not only results in better tool control, it saves you money by not throwing away tools before they are worn out. The depth of the hole in the handle determines blade adjustability.
