Review on Permatex 80190 SaferScraper: 2 Refillable Blades for Efficient Cleaning by Steve Griffin

It may be refillable but I couldn't find any extra blades here. The handle is made out of cheap plastic and flexes, making the tactile feedback terrible. The mechanism that holds the blade in place bends when you change blades, ruining something that wasn't very good anyway. So when you deploy the single extra blade, it wobbles and refuses to stay perpendicular to the hilt. I wouldn't recommend this and will just use Shark 66 plastic handleless blades instead. A useless tool that pollutes the planet. Should give 1 star but for the fact that the two blades were well made.
