I used this tool to thread the shifter on my Chevy Sonic which originally had a press on the grip. The photo I've attached only shows part of the work as it was cut flawlessly right up to the trunk. I would highly recommend this device as most of the others I found on the internet were only for "filament cleaning". Also note that the top half of the shaft was originally knurled, the bottom half was smooth but slightly wider. Easily cut through both parts.
