Had a long look through the forum (some great advice), and have whittled the choice down too these:
Parker 99R Butterfly Opening Safety Razor
Edwin Jagger DE89 - Obie I think this is the one you suggested?
Is there any difference between the two ? I would prefer the Parker just because of the extra length it has, but is the shorter Edwin-Jagger much of an issue?
Advice much appreciated! I may just end up buying both and trying each for a week.
