I found another unknown (to me) tool while cleaning a relatives garage out. It looks like some kind of marking knife, and I may use it for that, but really isn’t that sharp on the end and doesn’t look like it was made to be sharpened. First correct answer gets a free pass to one extra evening in the garage/shop with no interuptions. Thanks!

It looks like a coffin makers screwdriver or a cabinetmakers screwdriver. Both are similar in size and function.

Where are you? It looks like an oyster knife to me.

I think Keith nailed it.
The picture doesn’t make me hungry, like Charlie’s did. :-)

I would have to agree with the confined space slotted screwdriver.

Many moons ago, in a wood shop far far away, in a land that tool improvements had forgotten… before the torx, the phillips, and the square drive screws, there was the simple slot head screw. It was a time of great frustration and loud cursing in the workshop; it was the time of the stripped screw head. This mystery tool is an ancient example of the tool that tried to drive those old screws.

Some people still try and use these screws, some people refuse to accept that they are obsolete, surpassed passed the technological improvements of superior drive heads. If you look for the screws in stores you can still find these relics of the past. They are in the obsolete department, right next to all the tablesaws without flesh sensing technology.

I just checked your profile. If you lived in a coastal city, I would stick with my oyster knife guess. But seeing as you’re in Kansas, I guess the screwdriver explanation makes more sense. :-)

Keith got it. I’ve always called it a cabinet screwdriver. Now, Keith where did the term casket screwdriver come from? In all my years of woodworking I never heard that term. That’s not to say it’s wrong, I would just like to know were you heard it.

Jack-T, Straight drive screws and bolts are not obsolete, PHILLIPS are obsolete. I’ve had very few straight drive screws or bolts cam out on me, but I’ve had thousands of Phillips cam out. I now try to use only square drive. I tried torx but the cost was too high for the advantage.

Pop, the SPAX screws with a Bosch or square bit have been working really nice for me of late – no cam out and easy to put in by hand.

I was researching the term “Bench Dog” and ran across a site that had several pictures of the coffin/casket makers screwdrivers. I did a quick search and could not find the site. (Maybe I dreamed it)
I’ll track in down when I have a few minutes and let you know.
