Hey guys how do you preserve your sharpness? I found out not only drying my blades but also not letting my beard grow to much cause thats almost like double the work on the blade in my opinion. It sounds obvious but some people dont know. longer hair equals more work. just like when i use to use carts more blades really dull and bend etc under longer hair. I use to make carts last a long time but i love de shaving its more fun hope this helps
