Quick video of how to trim artificial grass/turf. This process (with oscillator) is WAY easier than trying to cut into the grass from the front side with a utility knife. Hit me up with any questions!
I don't know the exact brand, but this link is to the site of the place that I bought it from. The one I went with is call the "Half Moon Bay 84". They have the full spec sheet there. When it comes to turf, I found that the height and weight make a huge difference. 84 refers to the oz per yard. Heavier is usually better. This particular one has a 2in pile. Hope that helps! www.theturfdepotinc.com/shop-gallery-3#section-id-1617101688648
The initial two cuts you do are enough for guides, just use those to line up the cuts. Ps. That knife is shocking man, you're over exerting your hands by applying so much pressure.
I had an actual sod knife, which was a big hooked blade, but maybe it wasn’t sharp enough because it just didn’t work well. Is there a particular brand of knife that works best?
