For sale are three men's razors that belonged to my dad. I don't know their age. They are as follows: One silver stainless steel razor, the inside says "Gem Micromatic" trademark. The rear says "Pat nos.1739280-1773614". It opens by turning the bottom. The gold one is heavy (maybe stainless steel??) It opens by turning the handle. Inside it says "Star". The last one has a plastic handle and the balance is metal. I don't know how it opens! It says "Eversharp Schick". Their is a patent no. but I cannot read the whole thing. It has a dull blade in it. Smoke and pet free home.
