All right that narrows look down our search, I looked on it Amazon in couldn't find a $10 version, if anybody has a link I'd appreciate it maybe I'm missing something.thanksLooks like a knibbler used to cut metal sheets. You can get cheap version on Amazon around 10$
What gap width is needed for Gibbs blades? e.g. Knipex metal sheet knibbler has 2.7mm cutting width
