SWMIUSK 300mm High-precision T Square Ruler for Woodworking Marking Stainless Scribing Line Rule Carpenter Square Measuring Tool Metric Version

This came in so handy for my book folding project! Made it fast and simple. And if you've ever done book folding it takes forever. Lol. Made my measurements accurate. My project wouldn't have came out as good without it!

This ruler is excellent for book folding.I would have given it 5 stars, but I’m not happy with the pencil lead refills that come with it. The pencil itself is great. And, the lead that is already in the pencil is also great. However, the refill lead that is included is of very poor quality, not at all matching the quality of the preinstalled lead.I wish I would have known this prior to purchase. I would have ordered different lead ahead of time. Now I have to wait to finish my project.

I make kumiko and this 400mm precision T-Square ruler allows me to measure to the fractions of millimeters which are required for this work. I have other brands of higher cost and these perform just as well. Like the other brands, these do require a 0.5mm mechanical pencil for marking. This is not a problem for me as I require high precision in my work.

Perfect for book folding

I don't read paper books, I fold them. And this tool makes it easy and accurate to make the marks to bookfold. I did buy a different one that was longer to accommodate bigger books, but otherwise, this is perfect. I did end-up taking off the end piece and used washi tape to make a lip on the end instead.

Creates very exact measurement marks when used for book folding patterns. The only thing I did not like about it was the end could not be adjusted to move the ruler up and down on the anchor bar.

Easy to cut and use. Stretchy so best to cut Slightly shorter than you need.

** The company contacted me and issued me a credit towards the purchase of a pencil. Awesome customer service would recommend buying from this company.* Did not come with the mechanical pencil and pencil leads like it is stated in the description.

Good quality, highly precise measuring tool.
