If it came from Straight Razor Designs, do NOT strop first. They strop it for you!!! Practice lathering a couple of times before actually shaving - you will want a thick, creamy, almost meringue-type consistency to your lather. Start with just the cheeks (I did not have this advice when I started). Put the spine against your face, if it doesn't seem to cut very well, move the spine away a millimeter or so away at a time. Practice stropping with a butterknife BEFORE using that straight. One good way to start stropping is practice on a hanging sheet of newspaper. If you rip the newspaper you are stropping too hard. Stay safe and keep us posted on the progress!
