They are also sometimes difficult to grip, or impossible to deploy with gloves on. These sturdy nylon thumb tabs are designed to solve the problem. Each of the three tabs is uniquely designed to fit one of each of the three blades on the tool. Taking into account the blade thickness and fit in the tool. The tabs rise up a small amount above the surface of the tool. Dots on the tools echo the finish on the surface of the tool. Select from nine available colors. Order more than one set to use multiple colors. The tabs have a lightly textured surface, and provide a good grip. The nylon material is porous, and will darken if exposed to grime. Select a black color if you believe this will be an issue. The nylon material is heat resistant, strong, and long lasting.

They can be separated using flush cutters, or by simply snapping the sprue with your tool. Then file any remaining sprue material flat. The sprues are strategically located to be hidden after installation. Because each tab is unique: A symbol is etched on the back of the two smaller tabs to help you determine which one to place on the saw, and which to place on the serrated blade. [size=14px][b]Attaching the tabs:[/b][/size] The tabs are designed to be held in place using either super-glue or two small set screws each. [size=14px][b]Super glue method:[/b] Use super-glue ([/size][size=15px]cyanoacrylate). You will also need Acetone to clean up any overflow of glue.[/size] [size=14px]To install: Insert the tabs into the blade, ensuring they sit flush with surface of the blade. Flip the blade over and apply a drop of super glue to the seam between the blade and the tab. The glue will absorb into the plastic, and also into the seam. If any glue gets onto the blade, wait about twenty seconds, and gently clean using a lint-free cloth with a small mount of Acetone applied to it. [b]Removing super glued thumb tabs:[/b] [url=https://youtu.be/BkpekTSECyA]Click here to watch the video showing how to remove the thumb-tabs.[/url] Acetone can be applied to the back of the tab using a cotton swab soaked in acetone. Allow the acetone to absorb into the nylon, then wait about thirty seconds before pushing the tab out from the back side. Clean up any glue residue using more acetone. You can also soften the glue by gently heating up the blade to above 120°C. The nylon does not melt until over 200°C. (Do not apply heat directly to the plastic).[/size] [b]Screw method:[/b] You will need to source your own screws: Due to the way Shapeways works I cannot include the screws with your order.
