A: First of all, Jewelry Tools are ONLY for jewelry. Don't let your spouse use them for home improvement projects! Improper handling can scratch your tools and leave residues that can damage jewelry components later. Tools should only be used for what they have been designed for. Don't use bead crimpers as pliers, or nippers on memory wire. Wrapping the tips of your pliers in masking tape when working with wire can help avoid scratching both the wire and the tool. Remember, your tools are the most basic, most important part of your beading supplies. Treat them well.
