Greetings
If your razor has Eversharp printed on it that's a good sign IMHO, you know it is indeed one of the later models almost certainly a G Model, these are really nice shavers much gentler than the earlier E Models (which can bite) but even though they are more docile they seem to deliver just as good a shave.
It's an awful; shame that Connaught's are the one and only retailer of all types of SE blades in this country, I have nothing against them at all, on the contrary their SE blade prices are very good and their delivery times second to none, I would just like to be able to walk into a pharmacists and buy an odd packet of different types (both injector and SE) like you can in the states. I have to accept though that in many shops here in the UK they would lay on the shelf indefinitely.
Martin is spot on with the Chinese Schicks I have not tried them but all the stateside Injector users rate them as the number one blade made today. These are genuine Schick blades but produced in China (what isn't) having in the past been manufactured in the USA, Sweden and Germany and perhaps elsewhere!
Regards
Dick.
