First, some info on the Sharpal Knife Sharpener & Survival Tool from the company: 6 Functions: 1. Knife Sharpener. This pocket knife sharpener not only quickly sharpens very dull or damaged blades, but also hone for razor sharp; Not only for straight edge but also serrated knife. V-Notch slot (Coarse CARBIDE)-Quickly set a new edge; 2. (Fine CERAMIC)-Hone for a smooth finished edge; 3. Tapered diamond rod (Medium 400 Grit) for serrations & gut hooks; 4. Diamond rod with groove for fishhooks; 5. Ferro rod (This is the one I couldn’t get to spark.) 6. High-pitched emergency whistle.
From the Giz Wiz: The Sharpal knife sharpeners worked okay, especially for the size of the device. The whistle blew, the file seems useful on a camping trip, but, as you’ll see on this week’s show, the fire-starter seemed ‘spark-free’. I’m pretty sure I did it correctly after looking at their online video, but I could not get it to generate a single spark. UPDATE: When I did it live while we were recording this episode it did spark! So I think you should practice before you head out to a situation where you might need it to use. That way you’ll know what to do if you need to start a fire. It is a compact unit and it’s under $10.00. It received decent Amazon reviews too.
