I have a few OLFA utility knives that have held up really well. They were recommended to me by a tradesman. They're much sturdier than generic ones and it's really easy to find replacement blades. There are a few different handle handle / blade styles as well! https://www.amazon.com/OLFA-1071858-Fiberglass-Rubber-Utility/dp/B000N7EU1K/ref=sr\_1\_7?crid=23ACJ20815HSH&keywords=olfa+knife&qid=1665593461&qu=eyJxc2MiOiI1LjQzIiwicXNhIjoiNC44NSIsInFzcCI6IjQuNzEifQ%3D%3D&sprefix=olfa%2Caps%2C104...
The Speedy Stitcher comes with good instructions on how to use it. It's really difficult to explain, but once you actually do it, it's easy to understand.
I'd recommend practicing on another pair of shoes first if it's your first time.
Get this knife and a 10 pack of spare blades, it's an invaluable tool for this.

And remember to always cut away from yourself! You're going to be dealing with 4" of razor sharp steel. Just go slow and stop when you're frustrated, you'll figure it out.
Thanks! Using a 25mm snap off blade in a sturdy handle was really helpful. It made removing the old soles much easier. (OLFA 1071858 XH-1 25mm Fiberglass Rubber Grip EHD Utility Knife https://www.amazon.com/dp/B000N7EU1K/ref=cm_sw_r_apan_glt_fabc_07ACJFQM2X4VP2GAZGYB)
I'm glad to be able to help! I love repairing things 🙂
