>Sounds like a beading and parting tool. A aquare ended chilsel, that is beveled like a skew.
Not quite sure what you mean by a round bottomed skew. Are you talking about a round skew, one with rounded edges or a spindle master. I use both the flat, rounded edges, and round skews. I don't really have a preference either way for the rounded edges, I learned on a "flat" skew. And I don't really care for the spindle master. But if you really want to mess your mind up, get a triple point. But, only after you learn how to use a 'flat' skew.
>I had forgot about the oval skews. That may be what you are talking about as a "round bottom". I never found they were of any advantage in rolling beads. That is what they were marketed for. For me they are a little flimsy and no better at rolling beads than a square or rounded edge skew. If you are using a regular flat skew or one with rounded edges, I would stay with it. But, that is just my preference. Others swear by the oval or rounded bottom skews - its like Ford and Chevy, depends on what you drive as which is best.
It sounds like you've seen a skew that is ground flat across the cutting edge or 90 degrees to the shaft rather than the usual 45 to 60 degrees.
There isn't any reason you can't use a regular carpenters chisel except that the handle is too short. Most carpenters chisels are sharpened between 25 and 35 degrees which makes them kind of grabby when used as a skew. I usually demonstrate with a carpenters chisel when teaching the skew to show that all cutting edges are the same. I also demonstrate turning with a side ax, and a drawknife.
I think you'll find a woodturners skew to much more usable and user friendly. The longer handle gives you more control because you can use your body.
I've seen what some people call a "round skew". It's round on the bottom and flat on top. I built one to see how they work and it's really just a spindle gouge without the flute. It cuts slower and not as cleanly because the cutting edge is a less sharp angle. they are easy to make however so if you need a tool like that just find some high quality steel such as Drill rod and gring what you want. harden it and sharpen it and you've got a tool.
>It usually has a bevel like a woodworking chisel, but the angle is not so steep. Most square scrapers have a single bevel, but sometimes they have two, with a short bevel on top.
I suggest you look at woodturning catalogs or woodturning sites in the web. They have pics and descriptions of these tools.
Without looking at it it is just a guessing, as TD suggests, it may be a bedan, it is used to make cilinders, as in small tennons, but it can rool beads too.
About the aquare or round bottomed skews, the rounded bottom is more forgiving and it helps when you are rolling the skew, gives smoother cuts and if there is a catch, it does not dig into your tool rest.
>Hi Phil, the tool you are referring to is a woodturning chisel. This is the type of tool used by Peter Child, and described in great detail in his book.
He felt this was a superior tool in many ways to the conventional skew chisel. I use one also, I agree with much of his observations.
