This is probably the most essential tool set for working on a lever machine! There are 2 tools in the set, but the pick with the straight end/right angle one is the one you will use the most for almost all the gaskets & o-rings - removal, installation, scraping, scratching & cleaning, probing, poking (including making holes in your fingers if you aren't careful - they are sharp!). We consider this an essential tool. The 2nd one in the set, with the strange hook shapes...well, we don't use it much...but it comes in the set...what can you do?
