The only time I used one of these hook blades was to cut roofing where I removed part of the ridge shingle course to install a ridge vent. It was a pain pulling by hand. This would have made that and easy task.
For years I thought these oscillating saws were a non needed tool. But when you can plunge cut straight down in to oak hardwood flooring to install a new floor vent, and end up with a rectangular hole to the size you want, it really was a worthwhile tool. I did burn my harbor freight saw up plunge cutting a 2x4 for 32 inches, just too much time spent where I exceeded the duty cycle of the saw motor.
The other place they are handy is under a sink cabinet, where you need to enlarge or make a hole for the plumbing drain and supply pipes, you can get in where it's too tight for any other saw.
I wouldn't be caught without my osolating saw. I keep a good selection of blade shapes for many different tasks. They are great gasket scrapers just grind an edge on a worn out blade and have a go.
I hadn't noticed a hook blade attachment for them but this idea would be tons cheaper than a blade made for that purpose or just grind a hook into an old blade then hone it sharp with a Dremel tool
Thanks for sharing
I think you are really on to something with that idea! First time I ever saw one of these power tools was on a very old video (40 years ago?).It was a surgical procedure where they were cutting a bone protrusion (bunion) off of a patients foot. I think it was air operated. I had never seen a oscillating saw before.
Commercial versions exist. This Dremel variety...
has two edges permitting cutting on both the push and the pull stroke.
A slightly different version of the same thing...
The DeWalt variant has a larger diameter to move the tool farther above the material being cut...
