Hi, If you run out of your injector razor blades or something went wrong you can use this method. Even you can try to use different Double Edge safety razor blades with an injector razor. The choice is up to you
One thing to be careful of when cutting razor blades is they tend to bend a little and warp. Keep that in mind and check your blade gap for evenness
Thank you for the heads up, appreciated I noticed a bladegap evenness issue on my youtube video, because I was in a hurry but making the gap even is very easy in this method.
