Nice one, glad you are gonna give those razors a go mate!
Tip 1, don't buy a razor from curly H. Not that you would, now you have those nice ones.
Tip 2, find a good height to mount a hook to hang it from. I like the far end at hip height but there isn't a rule, just what works for you. Some like it higher so they can see the leather better while stropping. I don't recommend stropping 'downwards' away from you but flat or a bit upwards is good.
Tip 3, if you have it on the back of the door make sure the door locks. You don't want someone opening the door while you have a razor in your hand!
Tip 4. Rub your hand on the leather to remove any debris and add a little 'palm oil' (your palm not the tree!)
Tip 5 It doesn't need to be pulled super taut. But not floppy either. A little bit of bowing gives you more feel.
Tip 6. Find the right grip. Open the razor fully, hold the shank between your thumb and forefinger, cup the scales in your hand and practice 'rolling' it between finger and thumb in the air before going to the strop. It needs to be comfortable in both orientations with minimal wrist movement.
Tip 7, and this is basically "the instructions": Most importantly, ALWAYS keep the spine in contact with the leather. Go slow to start. Turn the razor on its back keeping the spine on the leather at all times. Draw it back towards you with very light pressure, spine leading and with the heel forwards so the blade travels backwards at an angle. Stop well before the end/fold/rivets as you can undo all your work with one hit. Never let the spine come off the leather or you will round the edge. Speed will come gradually, naturally. If you try to go faster than you can, you will get out of sync and end up flipping the blade before or after you change direction and you'll put a nick in the strop.
You should draw the blade gently at an angle, coming gradually off the side (X-stroke), as if you want to wipe the blade down the right hand edge of the strop (assuming you sre right handed). That way, you will cover the entire length of the blade.
Aim for about 50 laps before and after the shave. One lap is both sides/directions. The exact number isn't important but I find you need at least 36 (dunno why but I do sets of 12, all a bit imperial!)
You don't need to count, but if you do, find a way to keep a rhythm with the strokes you make. For 1-9 I repeat myself up and back (one, one) and in the teens onwards I count (thir-(flip)-teen) etc. You need the steady rhythm more than you need to count.
Hopefully that helps. Enjoy.
