Absolutely Repeatable Marking. Best Tool Ever for Mortises!,
I echo the words of the other reviewer. I use this thing all the time. It is the only measuring device I ever use when laying out mortises.
Try this with your ruler. Mark 3-31/32″ from then edge of your wood and then lift your ruler, move your wood around and try to use the same ruler to make the same measurement. I’m not saying it can’t be done, but with this thing, you can draw a .5mm line E-X-A-C-T-L-Y over the one you previously drew. It’s not off by a “hair” or a “smidgin” or “a little”, it’s dead-on.
By sliding the “fence” on this t-rule across your edge as you make your mark, it’s possible to make a repeatable and exact measurement from the edge of your board all the way down the length of the board in any increment (down to 64ths).
I stress repeatability because that’s very important when trying to mark two separate pieces exactly the same.
Since this ruler came into my shop, I occasionally amaze myself, and that alone makes it worth the price!

|Most used marking and measuring tool in my shop,
This was the first Incra product I ever owned. After a year, I realize this is the most used tool in my shop. It is well made. The lines and numbering are very fine and clear to read and the holes at 1/64th inch intervals and slots at 1/32nd intervals suitable for all kinds of marking with pencil or scribe knife. The end of the rule is calibrated or can be calibrated easily, so I can use it as a square for outter corners too. The stainless steel ruler body is thin but flexible and strong enough for various applications and eliminates inaccuracy from angled pencil.

|Accurate, Easy-to-Use Measuring,
I bought this T-Rule along with Incra’s marking rule and their “bend rule.” All are terrific and useful measuring devices, and I use them on practically every woodworking project I do. They are accurate down to 1/64″, and there are convenient marking holes at each spot. You can use these holes to make a perfect mark at the right measurement. Of course, it’s up to you to draw a perfect line across that mark and cut it on your saw, but the Incra rule helps you put down a perfect mark to work from.
In some of Incra’s brochures, they show a way to use the T-rule to mark your lines. You put the pencil into one of the marking holes, and then you slide the rule along the wood’s edge. As the rule slides, a perfect line is drawn. I don’t do this myself, but I see that it’s possible.
The T-rule is made of sturdy material, and it is dead-on accurate. The rule portion is flexible but strong. It can slide along the “T” section, depending on how you need to do your measurement. There are two adjustment knobs, which you loosen, then move the rule, and then re-tighten the knobs. When locked, the rule is held down securely and accurately. (As an aside, the “T” also has that trademark red color I associate with Incra products — it has a soothing quality for me.)
Although the rules are made of thin metal, they are very strong. I’ve dropped my rules a few times, even stepped on the T-rule once, and it didn’t seem bothered by it at all.
One thing to be aware of is that the measurements on this rule are in 1/32″ and 1/64″ increments. This means you have to convert into 1/4″ or 1/8″, which isn’t too much of a problem, but it is something to be aware of. It’s a fine trade-off for such accuracy.
Over all, this is a great product that can be used in every furniture-making project for accurate markings.
