Hilco Semi-Rimless Glazing Tool 20/055/0000

literally chipped the first lens i tried to use it on, i don't know if its a material issue, or if its just the fact that its metal but its not shaped well to go along the groove for tight strings.edit: turns out it is a technique issue, these aren't intuitive on their use as youll want to try using it the same way as the ribbons, either way, not as convenient as advertised.

I have been looking for this and such a good price.
