Are the twin blades twice the thickness of single blades?Brother fblais,
A twin blade can be used in a Schick Type I and a Type J if they are not the "hydro-magic" models, that is, if they don't have the lever on the handle that releases tension on the blade to expedite cleaning.
BTW a twin blade cannot be used in a Type G or earlier Schick injector. Twin blades cannot be used on non-Schick injector razors, such a the Personna and the Pal Injecto-matic razors. Schick twin blades came out at about the time the mild Schick Injector Type L was introduced.
Finally got the Personna blades yesterday!I had my first shave with my type J injector three days ago, and, while being extremely smooth, I found it was not quite efficient.
I had loaded a Schick injector single blade, brand new.
I have some Personna injector single blades coming from Connaught, maybe they cut more?
Very helpful info. I've got about 4 shaves on the twin in my L1, and I had heard these are VERY long-lived blades....given the number of razors I have and the lengthy rotation cycle, I may not live long enough to load another twin. Please keep those updates coming.Just a quick update from the eternal Twin Blade. The blade is still going strong, but the character has changed. Below the 'developments'
- day 1 & 2: blade is a bit rough, any pressure is too much and it is extremely easy to create a weeper
- day 3 to roughly day 10: extremely smooth & efficient and only needs very little pressure
- day 11 / day 22: slowly increasing the need for pressure, shave is smooth and efficient
- day 22 till now: use of normal pressure, performance does not seem to change a lot; shave is smooth and fairly efficient (it has however become sensitive to pre-shave prepping)
Brother Cyber,If you have an adjustable, inject a Twin into the M Type Adjustable. You can dial down the razor the first couple of shaves, allowing normal pressure to be used. Then crank it back up, as the blade smooths out. I shave the first couple shaves at around 4, and now keep it somewhere around 6-7. - I've long lost count of the shave number, but must be a good 10 or 12, and she's still going strong. Not my daily driver, but does see some usage.
