There are other SRP members who are probably more experienced at this than I, but imho a bad razor angle won't dull your blade to the point of not being able to use your razor, but it will not provide with the best shave.

If your razors aren't cutting your beard smoothly, check your stropping technique first. You may have dulled your blade while stropping.

As a remedy, get a second used strop and apply some diamond spray or CrOx and strop it 15-20 strokes. Then move to your regular strop and give it 50 strokes on the fabric and 55 on the leather. See if that helps at all.

If the preceding does not improve your razor's performance, then perhaps you'll have to get it rehoned.
