Saker Woodworking Scriber Marking Line Ruler, Adjustable Aluminum Alloy Sliding T-Square Ruler,Precision Line Drawing aid Ruler with Angle Adjustment Scale

I use this heavy duty tool on paper, canvas, wood, or any flat surface to accurately and efficiently mark layout lines. Very easy and intuitive to use. I find it easier to use with arthritis instead of more traditional layout tools. It has saved me hours of work and vastly simplified the task of creating borders and layout lines for drawing, wood burning, crafting. Very solidly built, very accurate measurements, and great angle function.

This thing is built like a tank. It’s solid, the angle decents work perfectly, the knob is a little redundant. The markings are easily read. The edges are all radiused and while nice and all that prevents the use of triangles with bevels because the bevels slip under the radius. I don’t mind the price given the very high quality.I have a drafting drawer with very little clearance so I removed the knob and cut the stainless shoulder bolt that holds it, flipped it around and threaded it in from the top. This eliminated the knob altogether but even when tightened down solidly the detents still allow the angle to be changed. It reduced the clearance needed and made it fit but the radiused edges prevent it from being perfect for my application. Since I changed it I will be keeping it.

Not of the highest quality, but worth the priceSquare is true as well as the 45 deg.

Some quick checks show the angles positions to be accurate and the 90 degree tee square is dead on. Positions are easy enough to find. I like the marking pen and spare leads of black and red. If the sliding marker was made of aluminum instead of plastic I would have rated the tool a solid five stars instead of a 4.95! This tool is a good buy and it will get plenty of use in my shop!

High quality product, with easy to read markings. A little frustrated with the lack of helpful instructions.

I would give this tool a higher rating if I could easily adjust it in smaller ( say 5-10 degrees) increments, instead of 15 deg. as the first position that has a stop. Good for most projects that do not require "absolute" accuracy on all the settings. but you are not paying the price for such a tool either. It may not sound like it, but I like the tool and can work around this issue so I consider this a good buy.

Great quality.

I like having a T square with the ability to mark a straight line accurately. I gave it only four stars because I haven't had a chance to use it much
