I am on the verge of not being able to see what I am doing also.
(Image removed from quote.)I used the saw blade to cut in a lot of recessed can lights this week because I like it better than my Klein drywall saw. However, that left the knife full of drywall dust and in a desperate need of cleaning. Also, the scissors spring has been sifting a bit when using the scissors, causing an annoying click. I think that I left out a washer the last time I reassembled it In addition to those things, the straight driver that resides between the scissors and can opener is of very little use. There is a straight driver on the reversible bit in the bit holder. When I first performed the mod I knew the driver was wasting space but I did not have a good idea of what to replace it with.For all of those reasons, I yet again disassembled the knife. I thoroughly cleaned it and then went to work on replacing the straight driver. There were three tools that came to mind that I could use: a prybar, an awl, and a chisel/gouge/scraper. Given it resides opposite of the bit holder in the handle in the middle slot, its replacement could be no more than 3/4" to 1" longer than the driver. That eliminated the pry bar. So, I chose to install an awl.I have my old Suspension laying around doing nothing, so I decided to rob something from it to make an awl. Unfortunately, the area around the pivot is too narrow to cut in a notch for the Multiforce tool lock. So, I started looking over my other MTs that I am willing to rob from at this time. Nothing with enough length and rigidity to make a good awl.Then I spied a poorly formed chisel/reamer on a Husky plumber's MT. On to option #3, the chisel/gouge/scraper. I sharpened the chisel cut on the end so that it would actually gouge out wood. I sharpened curved part of the tool so that it could actually remove burrs from PVC conduit. And I ground a chisel edge along the other edge of the tool. I forgot to take a close up pic of the tool, but it is visible in the picture above.In addition, I gave the scales another ferric chloride bath. The previous treatment was holding up well, but since I had it disassembled I figured I might as well do it.
I've taken this apart so many times due to putting something in backwards or leaving an important washer out that I believe I could assemble it blindfolded now. Zip ties are a great help also.Anywho, here's my half MF alongside the Gerber Armbar Drive and Slim Drive, a Rebar and an original Wave for size comparisons.
