Talking about different angles, I just bought a Vector 3 cartridge pack cause the mach 3 turbo was not available at the chemist.
The angle of both razors are quite different. The Mach 3 turbo has an angle closer to the skin while the vector 3 has such a weird angle that you have to move the hand up at right angle to get a close shave.
Quality of the vector 3 is mediocre compared to the mach 3 turbo. It's like rubbing skin with sandpaper and makes comparable noise too while cutting even a one day stubble. Mach 3 turbo slides on the skin like butter.
I'm referring to shave angle not blade angle. Blade angle has to do with how mild or aggressive a blade is when used. People have their personal preferences here. I prefer more mild or smooth to aggressive. My mind wanders all over the place when i shave so this is my thing. Aggressive means you better be 100% attentive and not in a rush or you're going to get cut.
By shave angle i mean you hit the beard from different angles. A with the grain pass, across the grain and against the grain.
This means going over the same area three to four times.
Clearly that won't be feasible with a multi blade razor as you will be dragging the equivalent of 9 to 12 blades over the same area. Number will be still higher with a fusion blade.
But with a double edge blade it will be just three or four times if you have your technique right and use a sharp blade. This technique part takes time to learn as you understand how your beard grows and from what direction.
Given these blades are cheaper tossing them after a few uses isn't an issue. Blunt blades can cause problems. How quickly they go blunt depends on who makes them or whether they have a special coating or not. A good prep, meaning beard is sufficiently wet and soft as opposed to less wet and tougher will get more life out of a blade. Less irritation, closer shave.
You will be able to get a better shave than what the finest barber could give you
Just see the prices of these triple blades.
Vector 3 is around Rs. 50 per
Mach 3 is around Rs. 120 per
Astra Platnums are Rs.14 per and these are imported. Local gillette will be still cheaper
