I would differ. It is the one of best tools for CA or plastic hinges. Years ago I used an X-Acto knife to cut the slots. Then along came the slot cutting machine. No more X-Acto for me. With your X-Acto knife, cut a small slit where the hinge will go. That slot will then be your opening/guide to insert the cutting blade and the slot will be made like a hot knife in butter. You'll love it
ditto................funny thing is, i am a millman by trade (a real cabinet maker) and i thought i was gonna ace the use of this tool right out of the box....LOL.....takes a bit of gettin to know it, but once figured out from test cuts, i'd never do without it.
i've used the guide, but found that by using a scribe and starting a groove in the wood where i want the hinge and then freehanding the SM into the groove worked a lot better.
