Review: CONVENIENCE - A great tool ! I had a plastic one 15 years UV was getting to it. It finally snapped, thank God !t This newer model far superior far more accurate be prepared to adjust yourself to understanding its capabilities. It has simplicities and it is very capable. It is a more advanced piece of equipment, great design and engineering equal by its correct material selection.!
Review: Very well built tool - 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 desertcart 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 rating ONE 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 me Is the left arm on Model #39 vs #29 The arm on #39 is way LONGER than Model #29 and also does not not come to a point at the end. See Pic #1 You CAN NOT obtain an angle as shown on the instructions #5. See Pic #6 Model #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.

### ⭐⭐⭐⭐⭐ Good value, sturdy, portable
*by A***I on March 24, 2025*

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.
