Using these Klein 11074 blades is easy. First, make sure you have the right wire stripper tool (it's not included). Simply replace the old blades with these new ones in your Katapult® Wire Stripper Cat. No. 11063. Then you can start stripping 16 - 26 AWG wires. When using, don't force the blades too hard as they are made to do the job smoothly. As for maintenance, keep them in a dry place. Since they are rust - proof, they'll last a long time. But if you notice any dullness, it might be time to consider replacing them again.
