Review: Best Drywall Tool - I never leave an desertcart review but this time I couldn't help myself. This tool is amazing!!! 10 stars if there was such a thing. It's cut my drywall scoring time in half, easily!! However this tool is best used for rip cuts. I used it on 4 x 12 sheets of 1/2" drywall and once I got the hang of it it it just got better. I started with a stack of 22 sheets on edge layed against a wall. I needed several sheets at 3 x 12. Grabbed the T square put my razor knife in the 12" hole and started scoring right to left. I'm right handed so that may not work best for others. After a few cuts I realized I wasted time by only scoring one side, snapping the drywall and then cutting the backing with an awkward reach under and around the waste piece. Its much easier to use this tool to score the front and back, then just snap it off in one junk. Way faster too!! Not really that good for cross-cuts but if you have a 4' drywall T-Square then you have what need. If I could add anything else it would be that the learning curve on this tool is really short and it will cut any dimension you desire up to 24.75 inches. Which means you can rip any width you want on 4" wide sheets. I might just buy a second one just in case this one breaks or my neighbor sees me use it and wants one for himself. Absolutely worth every penny!!
