Can never have enough tools. This is a quality one.
Saker 4-in-1 Scriber Marking Line Ruler, 29.5in Spliceable Extended T Square, Precision Line Drawing & Drilling Positioning Tool, Cabinet Hardware Jig with Angle Adjustment for Woodworking. Another quality tool for my collection. I've got other measuring, scribing, drill jig tools. Depending on the situation, one will always work better than another. So, this one expands my abilities. It is a well-made, heftier than usual tool. Looks like it should durable to last for years to come.

Great for diyers!
Nice scriber/T square. I used this to make cuts for flooring and trim work and it works great. It also folds and disassembles nicely so I can store it neatly into my work van. There are markers for angled cuts, which is a huge plus. Very easy to use and helps create accurate cuts. Good value!

Saker made a tool so versatile you that you'll need to read my review to understand it!
Want to complete your projects faster and with far more accuracy? Grab one of these Saker 4-in-1 measurement and guide tools! I tested the markings, all 100% accurate when compared to known good reference instruments that I own. It does more than they suggest: you can use it as a T-Square, straight edge, ruler, angle finder, hole drill jig and angle marker. It's so versatile and easy to use!

Great product. Great form and functionality.
This is a great product. It is made from anodized aluminum; black, with white markings in both metric and imperial scales. Not only does this look quite nice, but also makes it super easy to read the markings. It can be used in a couple different ways. Overall, this thing seems super durable. The aluminum body won’t break easily, even the plastic sliders seem extremely strong.

Great Mid-Sized Straightedge & Drilling Guide
Needing to drill semi-precision spaced holes to install all kinds of things, especially drawer-slides, cabinet handles, and hanging power tools, battery chargers, even drilling holes in an ABS box to hold an outlet, it’s pretty great to have a flexible, repeatable and pretty accurate guide/straightedge. It’s not quite a machinist’s tool, but it doesn’t pretend to be, either: it’s mostly for woodworking and utility uses.

Most Versatile Ruler I've Ever Owned
I love this tool! It is absolutely one of the most versatile “rulers” that I have ever used. Ruler is quoted because it is much more than that. Yes, it is a straight edge ruler, but the connecting rods and set screws join each segment allowing you to measure longer lengths. The sliding guide allows you to accurately position your drill. Everything locks in place.
