Replying to Help me make you a better park rider

How many times have you caught an edge on a rail and died?

I made a hand tool that detunes your edges FAST. It's super easy to use, but I don't know what other people want it to look like, do or cost.

Take a look at exhibit A. The orange part is what needs to be removed so you can slide like butter.

I need to know:
1) Is this something you want, or are you happy with using a gummy stone / file / beaver with lockjaw?

2) How much would you expect it to cost?

3) what are the top 2/3 features you would want out of it? (material, size, weight etc)

I appreciate your help!

I think I'm allowed to research on here, since I'm not blatantly advertising for my business that doesn't exist yet
