I just received a replacement RAT-1 from Ontario because I complained to them that my RAT-1 was difficult to open with my thumb using a slow motion or a thumb flick. I also find it difficult to close. In all of the YouTube videos on the RAT-1 everyone flicks this knife open as if it was an assisted opener.
The replacement I received today is more difficult to open than the one I sent back. I have loosened the pivot screw with no improvement. I have no trouble opening knives by Gerber, Spyderco and KA-BAR using the thumb flick.
Several YouTubers have complained that they also have trouble opening the RAT-1. One person said he needed a pry bar and a John Deere tractor to open his, but most seem to have no trouble. Any thoughts? Thanks.
