<br> <br> <br> <br> Secure yourself when you change the blades in your energy knife. While changing the blade, wrap tape around the old blade before tossing it in the garbage. By doing this, the sharp edges of the blade will be covered. When securing the garbage, or loading down the garbage, the sharp edges will not be able to injure anyone with the tape wrapped around them.<br> <br> <br> <br>
