A doohicky, and a pair of doojobies...

[Twilight Fenrir]

I picked up a box of misc. things at auction, mostly because it had a half dozen grinding wheel shapers, as well as a hand crank grinder. There were a number of other mundane, to slightly interesting things. But I've got one genuine mystery, and one slight curiousity :P

My genuine mystery, would be this... thing? I'm not sure if it's a tool, or an odd piece of hardware...



And here it is 'open' or... maybe closed?





And, from the side:



There is SOMETHING stamped into the side of it... but I can only make out a few odd letters... I might take some fine grit sandpaper to it later to see if it can be read... It seems to start with 'KLI????' With 'AG????' somewhere int he middle or end. With a patent number beneath it that appears to end in 1995...





Then there are these plier-like things... Judging by the build quality (not very good) I'm guessing it's made for a specific application, probably automotive. Looks and feels like something I'd find in the specialty tools section at my local auto parts store.

I think the top is for grabbing plate goods. But could be some kind of electrical because it looks like "Klein."

The bottom one is glass breakers / cutters.  The bottom wheel has several carbide glass cutting wheels.  After scoring you lay the v over the score and squeeze to break the glass.  They are supposed to work better on thick glass.

I bought a pair new at a sportsmans show a few yrs ago from a hawker.  They weren't as good as advertised.  I cut a lot of glass.

The first one looks like a  Klein tool used for pulling cable or rope,I believe they come in several  sizes to fit the different sizes of cable. I have a couple of them that we used for pulling wire rope,and they do work quite well.

1st, barbed wire stretcher.

Wire stretcher/clamp used by linemen in the stringing of telegraph/telephone wires...

I'm with GibsonTool — a cable clamp for pulling cable.  I own 2 (maybe 3, if I can find a big one that used to be around here) and have used several several times for pulling cable.  In your third photo down, the space between the parallel jaws in the upper right are where you place the cable.  Then when you pull the longish vertical-dangling loop to the left, those parallel jaws will clamp onto the cable.  It COULD be used to pull barbed wire but all barbed wire stretchers I've seen/used (a Lot) have grooves cut crosswise in one jaw so the wire won't slip.

Cable/wire pulling tool - probably from a linesman's kit, ex telegraph/telephone wires...

Second one is sold and used in the UK for breaking ceramic wall and floor tiles (generally under 8mm thickness)... Never tried using one on glass, it breaks easily enough without pliers....

Found it...

Yup! THat 2nd drawing is definitely it! Huh... interesting... and completely useless to me XD

A glass cutter, eh? Hmmm.... I guess it looks a bit more sturdy than the cheap plastic ones, but that's about it...

I didn't think that first thing would be found so easily! But, I guess that speaks to the people on here! Thanks for the answers!

I think I remember the seller cutting glazed tile with it also, the process is the similar. I was focused on the  glass use. Ceramic glazing is similar to glass, some is glass.

Glass likes to be ~6mm, or just under 1/4" thick.  I bought a sheet of tekta 6 mm clear, I had a hell of a time cutting it by hand with regular breaking pliers. So when this guy was cutting thick glass with this tool, I got one.

There is a big difference between plate glass and art glass.  I use primarily Bullseye coe 90 glass, plate glass has a coe of around 70 or 84-87 and is smooth as, well, glass!

I have diamond ring saws, and band saws, and all kinds of grinders, but I would love to find a tool that cuts softer thicker glass.  After I fuse glass together it is usually ~1/4" thick and very smooth. I hoped this would be a good tool for the job, but oh well.

BTW COE = coefficent of expansion.  It is a simplified way to describe one of the factors of glass compatibility for fusing together.  I like to use coe 90.  Others use 96. Lab glass or borosilicate glass or corning glass has a coe around 32 or 33.  Soft glass like moretti rod is coe 102, 103.

Float glass is called float glass because that is what it does, it floats on molten tint. Thats how it gets such a smooth surface.

So, I agree that smooth float glass is very easy to cut and break, especially in single width. Thicker glass, art glass, and coated glasses all cut different. Believe it or not, in my experience, compatible glass of different colors cuts differently.

So, in my use the tool like the one shown wasn't better at cutting glass.  Maybe it does a better job with tile? I need to give it a try!

> Maybe it does a better job with tile? I need to give it a try!

Ordinary glazed tile is softer on one side than the other, that makes cutting it more forgiving, I suspect that tool works great for tile, probably lousy for glass, it is too broad at the bottom and will induce flaring.

Cut pyroceram some time, man is that stuff fun, you can jump up and down on the scribe and it laughs at you for a while, then eventually runs...maybe..
