Greetings. Can anyone shed some light on this tool. A file holder for filing edges perhaps. No makers ID or numbers. I would like to know the age and where it was made. Thanks

I was thinking maybe jig for planer blades but card scraper makes more sense.

I would agree with file holder, for edge work, like jointing saw teeth before sharpening. Is your aluminum or cast iron?

Thanks for that picture, mine is cast iron.

A skate sharpening tool should have a round stone, not a flat file. I think flyingblind might have it right. Looks like a tool for sharpening a card type cabinet scraper.

The "stone" @Old Man Roger refers to is #9 in the patent drawing below. I did not know there was such a thing as an "Ice Skate Sharpener" until a couple hours ago. Interesting rabbit hole.

The OP's device is for a different purpose.

Yup, from what I’ve read on the net some years ago, the down side of a good ice skate blade, well sharpened, is a tiny inverted U. Forget the why and wherefore, but something about a tiny bit of water melts into the gap, and allows you to glide on water. The ice usually reforms behind you. (And after enough of that, Mr Zamboni comes to the rescue.)

And good sharp blades will cut you while handling, or so a friend tells me.

They're concave, but shallowly.

They are extremely sharp. It's common to slip on rubber blade protectors. Modern ice hockey skates are done on a machine, though. Finding a good blade sharpener is something of a mythic storyline in any ice hockey circles, amateur to pros. There are pros who still use sharpeners at their former clubs. Too sharp is worse than too dull for skating. You can dig harder to make up for too dull, too sharp will make you look like a fool.

I'm guessing you're not aware of the tragic freak accident that happened in a game in England last year. After a multi-player collision, former NHL'er Adam Johnson was prone on the ice and slid into the skate of another player, also prone on the ice, and his neck was sliced open. Never made it to the hospital.

Heard of it, preferred not to talk about it.

Going off hearsay from someone who needed stitches after careless handling. Skating for amateurs is not big here in the bay area, tho some pros have come from here .

Skate blades have two edges, used by skaters much, much better than I to pull off some amazing agility on ice. Look for a YouTube vid that’s something like “Sydney Crosby’s edges”… anyway here’s a fairly good explanation… it’s not necessarily HOW sharp (you want them sharp) but the size of the hollow. Smaller lighter players usually use a 1/2 hollow and heavier guys can go up (3/4 is another common grind). The heavier you are the more that edge “bites” the ice, so you make it a bit more shallow so it peels ice rather than driving in too deep and sending you high-side.

But with regard to the OP, definitely not a skate sharpener with a flat profile like that. Deburring stones are flat but not what grinds the edges.

I have found another one, in a museum, used as a paper weight. They said it was a reel mower sharpener. What do you think?

GROAN!

I've resharpened several well-abused reel mowers. It's a PITA! The reel and cutter bar work like a pair of scissors, using the helical angle of the reel to slice the grass against the stationary bar. Hence, a properly sharpened reel is 100% concentric. A lathe woud not be out of place for sharpening one.

A good, sharp, well-tuned reel mower is the finest grass cutting device in existence. It leaves a perfectly uniform cut depth with no tattered leaf ends to brown. Power reel mowers, usually gang mowers, are what's used for professional athletic fields, as not only do they make the perfect cut, but they lay the grass down uniformly and directionally, which is how you get the patterns you see--grids, cross-hatch, etc.
