Rated 4.0 out of 5.0 by Tom3 Some helpful tips to get more out of these clamps
This BORA Clamp Edge set is well-built, sturdy and doesn't bow and fastens quickly to help use it as a guide for your circular saw, jig saw and router. You can also use it as a fence for table and bench tools.
This set comes with a 24", 36" and 50" Clamp Edge. The 24" is good for cutting small pieces, the 36" for trimming the bottoms off of doors and the 50" is good for cross cutting full 4' x 8' sheets of plywood. BORA also make a 100" clamp for ripping full sheets of plywood which is not included in this set.
In addition to being used as saw guides the Clamp Edge can also be used as a quick bar clamp.
I found the single instruction sheet that came with the set a bit confusing. The thing that confused me is that on the movable jaw, the back piece moves in (closer to the jaw) or out (away from the jaw. For the jaw to slide freely it needs to be pulled away from the jaw. I was able to start using the clamps to trim some DriCore panels the same day I received the clamps after figuring that out.
Compared to other saw guides I've used in the past the BORA clamps are quicker and easier to set up. As a fence it is very stable and provides a thick surface to guide your tool. They can also be set up at an angle. I was a little worried getting the clamp square would be a problem because the jaws swivel but I tested putting the clamps on multiple times and checked it with a square and it was good each time. I'm still going to check with a square before I make a cut just to be safe. Measure twice, cut once and all. :)
One issue with saw guides like these is you need to offset the clamp from the cut line. That means you need to know the distance from the cutting edge of your tool to the edge of the tool fence. You can easily make a spacer that doesn't involve measuring and remembering the distance.
Here's an example for making a circular saw spacer.
1. Get a piece of 1/2" or 3/4" scrap plywood and clamp the BORA clamp on it to make a cut. It doesn't matter where you place it as long as you leave enough room on one side the width of saw's base plus a little extra.
2. On top of the scrap piece of plywood, place a scrap piece of thinner material such as 1/4" plywood or 1/8" tempered hardboard that is wider than the saw base plus a little more. The height of the scrap only needs to be a few inches. Press one edge flat up against the fence and clamp down the opposite end with something like a quick clamp or c-clamp.
3. Adjust your saw so that it cuts only through the thinner sheet of ply sitting on top of the thicker piece. You don't want to cut all the way through both pieces. Then make your cut with your circular saw on top of the scrap and pressed tight against the Clamp Edge fence. Label it so you know what it is. Ex. Circular Saw Wide and draw arrows to show wich are the 2 edges to use.
Repeat the process using the other side of the circular saw so you can cut either way. (The distance between the saw and edge of the fence is different depending if you're using the left or right side of the fence.) Also do it for your jig saw, router, etc.
Now when you need to cut a piece of plywood, draw a line where you want the cut. Place the spacer so one edge (that has an arrow) is on the line and then bring the clamp tight up against the other edge. The clamp should be on the "keep" side of the cut so the cut is on the waste side. If you accidentally put the clamp on the waste side the piece you cut will be thinner than expected because of the saw's kerf.

Rated 5.0 out of 5.0 by tnahpele Good idea nicely implemented
These clamps/edge guides are well built and clamp firmly. The guide bar is aluminum. The rubber-padded clamping jaws appear to be plastic resin. The movable jaw clamps firmly onto a steel rod. The steel rod, in turn, is moved by the clamping lever to tighten the clamp. The clamping lever has 4 positions with a total of 3/8" clamp movement. While the locking mechanism for the movable jaw looks like it's plastic, there are 3 metal plates that lock securely to the round metal rod.
The movable jaw locks when pushed closed. To unlock the jaw you have to pull it open. This is counter-intuitive when it's not quite tight enough and you want to tighten up the jaw a bit - you have pull back to unlock it before you can push to tighten it. If I just push firmly in the first place it tightens up fine.
When used as a guide, the adjustable left-right angle of the jaws might require some fiddling to make sure it's set to 90 degrees. Since the jaws are self-centering, with the 24" clamp you have to work at moving clamp off-center to set it to an angle other then 90 degrees. With the longer clamps you'll need to use a square to make sure they're set at 90 degrees. Another thing to be aware of is that at their largest opening, the clamps measure 1/2" less between the jaws than the rated size of the clamp. For example, the largest opening between jaws for the 24" clamp was 23.5".
The product page and manufacturer's website says it has a lifetime warranty but there's no mention of a warranty on the product information sheet included with the clamps, although the manufacturer's contact information is readily available.

Rated 5.0 out of 5.0 by schlafe easy to use rip / router guide / straight edge...
Great product to use as a straight edge when ripping plywood or other sheet materials. Also works well as a router guide. The clamps are lightweight, durable, and easy to operate. The locking mechanism works well and all moving parts slide effortlessly. I am sure there are many more uses for the clamp set but I am satisfied with the straight circular saw cuts and cleanly routed edges.
I would recommend this product.

Rated 5.0 out of 5.0 by kharndt So easy to use
I recently did some work in the laundry room and had to cut a plumbing access door out of 1/4" plywood. These clamps are sweet, so easy to use! I had some difficulty at first squaring the clamp on the plywood because the head swivels to accommodate cutting on an angle, But, after a couple practice cuts, I got the hang of it. Anything to avoid hauling out the table saw!

Very easy to use right out of the box. I can finally cut a straight line with a circular saw. Well worth the investment.

Rated 4.0 out of 5.0 by Bill1974 Simpler than a straight board and couple of clamps
These are nice cutting guides. They clamp to a sheet of material easily and have good holding strength. They might be a challenge to use on 1/4" ply but I think you could get it to work. The longest one will flex if you push on it, but if you are using it with a circular saw it should be fine. Not as accurate as a track saw, but for breaking down sheet goods its a lot less expensive. Using a router with the long guide on a 4 foot wide piece of material will cause a noticeable amount of deflection, unless you are really careful. Another is to back it up with something to see if you can get a clamp on the middle of the guide.
Storing this is easy, I like to clamp them smaller ones into the larger ones, this way they all stay together.
