Great for getting in the space to free the window and removing paint from the frame.

This Hyde window opener is a straightforward but essential tool if you need to safely open painted or stuck windows. It’s well-made and sturdy, with a thin but strong blade that easily slides between window sashes without causing damage.I’ve used it to break old paint seals on windows that hadn’t been opened in years, and it worked perfectly. The handle is comfortable to grip, and the tool feels durable enough to last a long time.No complaints—it does exactly what it’s supposed to do! If you’re dealing with stuck windows, this is a must-have.

The pic in the listing looked kinda sketchy, but ordered it. Got it the other day. Cold weather so not wanting an open window, but did one of the painted closed windows just to experiment. Took 5 minute or so to break the paint seal with this tool, its like a thin saw blade, the teeth go one direction on one side and other direction on other side so you do left and right sides of window.Will mention you will need some lube for the window. I got it open from outside with help of a wonderbar prying against bit scrap wood. But it wasnt like it just immediately went smoothly up and down. Took few applications with some light mineral oil. Now have it so it will go halfway up and down easily, but needs more work to freely travel fully open, then easily shut.But the tool, yea just the convenience worth the price. Could this maybe be done with an old serrated knife or something, probably but this is designed for doing this. One window, use the old steak knife. Multiple windows, buy this and whatever kind lube you prefer. I am thinking for other windows, may buy some slip-plate graphite paint, better than petroleum product for this.

I live in a house built in the 1880s and the windows on my porch have multiple layers of paint. I tried and tried to get the windows open with various other tools I had around the house, but no luck.I was about to buy chemical stripper but when researching what would be the best brand/type to tackle 50+ layers of old, probably leaded, paint, someone recommended this lil guy. At first I was skeptical, because I had a thin blade of sorts that I already tried and it didn't even loosen up, but for less than $20 it was worth a shot.This buddy sliced through the layers of paint on the inside of the porch windows like it was nothing! The layers on the outside, I had to put my back into it, but I think there were more layers there. Either way, I got them open! 4 down, 6 to go!

Our house is 90 years old but new to us. Last year we had one window we could open. I stumbled across this tool while researching how to get the wooden double hung sash windows to open. As it is so thin, it slips in between the sash and the stops. You then gently rock it back and forth while moving it upward or downward. It cuts through years of paint or stain without cutting the wood. The beauty of this little tool is that you don't want a lot of force or pressure to use it. It takes a little practice but I have now opened six new windows with it and have three left to go. I have needed to use it on both the inside and outside to make them open so it has got a lot of use. It is still in working order.

This tool works like a charm for me! You just grate it along the seams where the window has been painted shut (on both sides). It might take a little bit of extra elbow grease but I'm an average build 40-year-old woman - so nothing too intense.Then I greased up every seam and along the frame with WD-40 and used a crow bar to pry up. Instead of going right in the middle and forcing it up, I just gently pried it a little bit on one side, and then again on another side, just to kind of ease it without cracking the woodYou hear a satisfying "pop" when the window finally lets up. And from there I grease the frame even more and sand down the areas it runs along so that it opens and closes smoothly. It doesn't take more than 15 minutes.I don't know how long my windows have been painted shut but the house is 70 years old, and I can see two layers of paint so I'm guessing at least 40 years since these windows have been open. So far I've done four windows and not had a problem with any of them using this method. I'm sitting next to the window right now and feeling the cool air - just SOOOOO happy to finally have them open!

I used this on a painted-shut window that I’d already tried to cut open with other tools. This one is great because you sort of ratchet it forward bit by bit and the teeth cut through the tight parts - no real sawing motion necessary by the user.And it worked exactly as advertised! I used it all around on both the inside and outside of a window, 20 minutes later the window was sliding up for the first time since we’ve owned the house (and a long time before then!).I’m very pleased!

Easy to use & light weight. Edge is sharp so be careful not to slice into your window like I did.

Have used this tool to cut through the paint on our windows that had been painted shut. It worked very nicely. It works well getting it in around the edge of the window and then tapping the back of it with a hammer or rubber mallet to push it through the paint and cut it.

This was the ONLY thing that could get my heritage home’s sash windows open. I put off ordering due to price and figured I would only be using it once. It got to a point where I could not take the frustration any longer so I ordered this and BOY did it make my day when I finally opened those damn windows.

I used the HYDE TOOLS #45200 Window Open Tool to open three windows that were painted shut on a 60+ year old house. On a prior attempt I used a standard utility knife,a putty knife, and a wood chisel without success. At a loss to open the stuck windows a professional house painter told me I needed the right tool for the job. I bought the Hyde tool on line from Amazon. After "on the job" training I began to make headway. The tool had a spear point with "saw teeth" on the edges. A sawing action cut the old layers of paint on a wooden window frame. The blade is thin enough to work between the window and frame to cut through glue like old paint holding the window shut. A word to the wise, it only cuts paint, it won't take abuse from prying. The metal handle on mine cracked above the rivets. I used a borrowed "wonder" type blue pry bar to pry the window open, I don't remember the brand but it a more useful design than my old model pry bar. I used the excellent Bessey folding utility knife to cut a groove in the paint to start and finished up with the Hyde tool. I would buy another HYDE Window Open Tool without hesitation.
