This is a pair of Diamalloy wire cutters/strippers.  The three holes designed for stripping appear to be all the same size, and for something close to #20 wire guage.

It is difficult to make out the part number on these.  It looks like it's something like SN5R or S55R.  They are spring loaded for ease of use. There are from tools I had purchased over a number of years.

I am now just clearing or extra tools that I had accumulated.  

Please note that the 6" metal rule in some photos for scale is NOT a part of this sale.

I will have a number of pliers, and other small hand tools for sale.  If you purchase more than one item, I will gladly combine shipping to save shipping costs for you.  If you do purchase more than one item, wait until I send you an invoice with the combined shipping cost.  Ebay's system often doesn't combine shipping very well.
