Do you have an old razor you love, but out grew it a bit because its a little to mild for you ?Well there is something you can do about that, you can shim the blade between your baseplate and the blade itself and its super easy to do toolet me show you how, first get an old blade you are going to throw away and a regular pair of scissors, and simple cut the edges off as close to the end as possible, it cuts just fine believe it or not will be like a piece of cardboard,then just assemble it together with the cut blade shim, towards the safety bar plate, and the sharp blade towards the headand you will increase your gap, and have a more aggressive razor, i did this with an old type that usually sits the blade flat on the teeth, i had to monky with this pic to get the shade to show up a bit more but you can see it has more of an open gap then beforeyou can shim with as many blades as you need to get a great shave, each blade will make it more aggressive im going to try two shims myself next time out with the old typehappy shaves guys !
