Available in 6" or 12" sizes, metric and imperial. Made in the USA.

Designed To Be Everything But Ordinary. While continuing the tradition of quality and accuracy that has made Woodpeckers precision squares the standard for woodworkers, the 641SS and 1281SS push what is possible in tool design. Equipped with a sleek, adjustable stainless steel blade, these multifunctional precision squares enable faster and more accurate measuring, marking, and scribing. They are simply some of the best squares we have ever made.

What's the advantage over the 1281?

Stainless blade is thinner.  Also looks like the blade has holes laser-drilled to allow you to run parallel lines along the edge of the work piece.

@Shane Holland - even though they offer a metric version there is zero info on it either on their website or in the video. I assume the notches are @ 1mm increments, but before ordering can you confirm this?

@Richard/RMW

Yes, 1mm increments for the metric. It's kind of buried in the description text.

"Perhaps the most eye-catching design feature is the laser cut notches that run along the length of the blade in 1mm increments."

Thanks Shane - should follow my advice to the boss and "read all the words"... 

Ha, yes. I have turned into quite the "skimmer" instead of reader over the years. So, I am also guilty of missing some important details sometimes.

I agree with the post above, that "feature" turned me off this square instantly when I read that.  Yeah, you can send them back but who would ever do that for a square.  I will keep my 1281 thank you.

I've got news for you.  The 1281 style squares get out of square all the time.

Woodpeckers states the following...

"Our Guarantee. We're so confident in the accuracy of the 1281 Square we offer it with a Lifetime Guarantee to stay square to within one-thousandth inch or we'll repair or replace it upon return and inspection by us."

I don't have both toes in the metric pool and $10.00 is $10.00, the saving if you buy both models. So is there a mix and match option?  One 12 inch and one 150 mm?

The 150 mm seems just the ticket for working with Domino depths and track saw blade heights.

I recently had to mill a set of boards for a table top. The stock had very rough edges with some deep raggedy indentations over the board length.  The scribing feature on the 12 inch appeals for finding the width of boards needing extensive side trimming on my table saw which is set to inches.

Isn't the adjustment feature accomplished by drawing a line and then flipping the square? Seems simple enough without going to a second square device.

I like the larger more workable scribing holes. The Incra rule is just too hard to locate the right hole.  Plus, I am not that comfortable with a mechanical pencil these days. Of course I grew up using flat carpenter's pencils that needed a whittled point. These mechanical pencils seem so girly man.

You can use any method you want to check a square.  That part is irrelevant.  Most people do not have expensive test equipment.  Even a calibrated Starrett engineers square can get out of square.  The drawing a line and flipping is a method anyone can use. 

Same guarantee for both 1281 squares, remember?

If it is made of multiple pieces, it is adjustable!  Even the standard 1281 square is movable and adjustable.  This is why I prefer the one or two piece triangles instead of the three piece "L" shaped squares.

@Cheese How do you know your 12" Starrett is square?

No the Starrett is not adjustable. It's only considered adjustable because you can exchange different length rules and you can also add additional attachments. Once locked-up however, it is what it is...it's either on or off. If it's on (like they have been for the last 100 years), you're golden, if it's off, you just chuck it in the trash. Thank God they're the former rather than the later.   

I did not say anything about the Starrett being adjustable.  How do you know your Starrett is square?

Nowhere does it say that you are expected to calibrate it yourself. It says that if you drop it on concrete numerous times over the years and find that it slips, you have the potential to calibrate it yourself as opposed to throwing it away and buying a new one, as I've had to do with two hardened Starrets that vibrated off the table, hit the floor and were never square again.

One piece or multiple pieces, metal moves. It moves less than wood tends to, but it is very, very, very far from anything approaching absolute dimensional stability.

Some peoples' senses of entitlement obviously never change shape. It's too bad no one can make anything useful out of those.

In every ISO certified manufacturing facility, as part of the yearly ISO engineering validation process, all measurement tools are pulled from ALL engineers and are verified according to the company's ISO specifications.

In my particular case, I used my own personal measuring instruments (scales, squares, calipers, micrometers) to verify the measurements that were collected by the QA group. Thus, if I was to approve and release product, I needed to insure that all QA checks were conducted with ISO certified equipment. Bottom line is that my personal measuring instruments also needed to be ISO certified and that was on a recurring 1 year basis.

Hey @RobBob, forgot to add, both of the Starrett squares were acclimated to the test lab temp overnight and then compared to a granite cylinder. Pretty typical...

...as I've had to do with two hardened Starrets that vibrated off the table, hit the floor and were never square again.

You're exactly correct, these are cast/forged pieces of metal that when they hit the floor they're usually toast.

Like everything else in life there are pluses and minuses. My personal preference is to pick up a tool and knowing that I've not dropped it on the floor or jammed it against another item or damaged it...well then it's square...simple. My least favorite option is to second guess myself and to remember accidentally slapping the square into another solid object and wondering if the squareness has been compromised. Then it's into the test mode which just takes time and slows the process.

 There have been innumerable stories told about measuring twice while cutting once yet the dimensions were still off for some reason. 

The adjustability of this square should be seen as a positive. As others have said, if you have a square that's not adjustable and it gets dropped or damaged, it's junk. With this one, you can re-calibrate the square, if needed.

Woodpeckers says this square is accurate within .008 degrees.
