Having just finished tweaking the nosepieces on my new sunglasses into shape, it’s worth mentioning a few pliers you should have.
This set of pliers (PN HH02075SET) from Circuit Specialists is absolutely invaluable. Mine were about twice the current price; the picture looks the same.
You’ll use these four metal-forming pliers (PN 60398) from Micro-Mark somewhat less often, but when you need ’em (like for adjusting your glasses), you need ’em bad. Mine were about half the current price, but I’m sure they cost the same in constant dollars.
I picked up a bunch of surplus Plato 170 flush cutters a long time ago, but even their current price isn’t too forbidding. Great for circuit board work.
Invest in tools: put your money in metal!
