Are there advantages with DE or SE blade systems that are available to a person thinking about getting into traditional shaving and there is strengths and weaknesses of any blade system. I started out with DE razors and still use them with my ever growing razor collection. Of the blade systems that are available to a Newbie or seasoned shaver are DE , injectors, Gem blades and AC (Feather,Kai,Schick proline SE.) blade systems. DE offers a huge assortment of blade coatings & pricing while SE blade coatings are limited but are still MFG today in various Country's around the globe. SE blades tend to last 30% to 50% longer for decent shaves IMO and are generally more expensive and Gem blades being the best $ per shave value if your buy 100 pcs(bulk). DE blades per shave run around $.02-$.04 cents per shave and Gem Personna blades are about $.02-$.04 cents per shave and the other blade systems are a little pricier IMO. Personna injector blades can bring the price per shave for $.02-$.05 when buying 100 pcs(bulk) and that is awesome for a injector system. Blades for DE are more available and the bulk of shavers world wide use the least expensive systems it seems. I find in winter months when it's drier and beards are tougher the SE works the best for my daily shaving needs because of thickness and sharpness of blades. There are still modern MFG's making SE razors and lots of DE MFG's of razors so it's not a problem finding blades for the systems mentioned. I personally have DE & SE razors and just loving it with a lot of vintage razors of both blade systems also. Have some great shaves!
