General Tools Protractor and Angle Finder #39, Stainless Steel, Outside, Inside, Sloped Angles, 0° to 180°

My 1st General Tool Protractor and Angle Finder was the Model #29. I decided later on to get the Model #39. Primary reason, it's a stainless steel version instead plastic. Both models are essentially the same. #39 is larger than #29. Both in the arms and scale angle head. Refer to Pic #1 for the size differences. With the #39 scale head is larger in size. Those spaces between the [ degree of angle ] became larger too. In my opinion, make it easier to read. One major advantage #39 has over #29, is the larger opening the angle indicator arm, Pic #2 & #5. Model #29 is very difficult to read, and had to make some revisions on the indicator arm. --- See my amazon review on GENERAL TOOL No.29 for those details. ---There is a review ' stating ' that scaled marks on this tool are etched.The one I received contradicts this. Only ' one piece ' was actually ETCHED, see Pic #3 for details. The rest appears to be masked painted. It appears to me that the non-etched components might have been clear coated. In which should help with durability of long time usage. Time will tell.I seen another review about how stiff / hard to move the tool in different positions. The one I rec'd was stiff at 1st, it has free up the more I use it. Refer to Pic #4, backside of tool. The arched hole is die stamp cut out. Some had said there is a bur from the cut out. Thereby causing the tool to be stiff or binds during movement, where one person had to filed the edges to make it smooth. Again on the one I rec'd, those edges were pretty darn smooth. Some say oil the pivot joints.I have more less use the tool right out of its package and ran with it. Not saying others didn't had problems at first.From my perspective and opinion ' ONLY ' this protractor angle finder tool is well built. And deserves a 5 ratingONE absolute major improvement is the ' how-to-instructions ' for Model #39 see Pic #6. Model #29 is more worthless than cheap @#$% thin toilet paper. Probably one of the most poorly illustrated ones, that I have seen for some time.Cons: A big one for meIs the left arm on Model #39 vs #29The arm on #39 is way LONGER than Model #29 and also does not not come to a point at the end. See Pic #1You CAN NOT obtain an angle as shown on the instructions #5. See Pic #6Model #29 does this job far easier.Pros:Again in my opinion, this tool along with Model #29 can do more complex angles than most other tools that I have seen anywhere at stores or online vendors. As I have said many times in reviews, "I buy tools that make my job / work easier.Hopes this helps you.

This has been a little lifesaver - I need a portable protractor for odd angles for the work I do, and this has definitely made work a lot easier. Seems to be fairly sturdy and accurate so far. Good value.

I decided to replace the fascia on my house and I have a lot of different angle roof pitches. This little tool probably cut my installation time in half. It is really good quality and does not slip once you secure the angle with the thumb screw. Obviously it cost more than the plastic ones but it is by far superior I highly recommend it

I would purchase again.If you are looking at exactness in number, I'd go another route. It holds an angle we'll -copy an angle just fine. It has some looseness in the hinging.... not bad if you're not picky... (spend more $). As you arrive at a straight line there will be a greater inaccuracy. Engrading: the rules are deeply cut. The compass is much lighter, I believe due to keeping the lines accurate... per photos you will see they are very clean but hard to read for a guy needing bifocals..go figure! They are not printed but Lazerd!! With all that said it's a great tool.Tuneup:First thing I'd do is oil the rivet-hynges.Remove the Thumb nut and flatten out the hole punch on plate back dimond file etc.. it has a sharp ridge. It will add 5bucks to the feel!!Lastly check it with another square tool and compare its exactness.Definatly worth 13$. I'm cuting fire bricks with a recalled Rioby slide saw Haha!The angles need to be right as when tide together they will need to make a good 10 batt circle. So not so much reliant on the angle numbers on tool but tracing existing ones on my fire bricks.Spend a little more on this than the cheaper plastic one. It'll respect you back if you're nice to the tool.

Used this tool to measure some angles between structures (concrete, wood). Works great, accurate to within 1 degree. Can lock in the measurement with a thumb screw and read out later.

Versatile and easy to use. I had the plastic version which was just as great and sturdy until a friend knicked it with a saw, compromising its accuracy, so I sprung for this metal version and am just as pleased!

Good for priceKinda rough and flimsy

Works perfect
