Try this too
Take some wet dry sandpaper and put a little mineral oil on it.
Rub a bbw slurry stone on it and make a thick slurry paste.
Transfer to a strop to make a bbw strop. Make sure you even it out like you would chromeox.
Back in the coticule.be days we were trying this, some guys liked the results. Bart said the razor didn't pass any HHT but the shave was excellent.
You can also try yellow coticule slurry.
