Manual razor enthusiasts, in the end often go to the "safety razor" direction.
Safety razor is not really the literal meaning of safety, it is named in contrast to the earliest straight razor.
Yes, it's the kind used by Sweeney Todd.

Using a safety razor requires some manual shaving skills.
Hot compress, foam, scrape along and backward, apply aftershave, and it is best not to drop the same.
In contrast to the audio field, the safety razor is like a vinyl record,
It doesn't make sense to use it for efficiency, but the ritual of life is very sufficient.

In this day and age, using a safety razor has another meaning.
As a consumable blade, it is pure steel without plastic.
Note that I am talking about consumables (plastics used in general products are still difficult to replace, and the topic is very big, so I will skip it for the time being.)
The environmental impact of not containing plastic should be very positive without accident.
And it's really cheap. There are better brands on the market with a head of more than ten to dozens of pieces.
But a safety razor blade, tearfully sold you a piece is already blood earned.
Life is not easy, everyone can save.

General safety razors are double-edged. One disadvantage is that it is difficult to determine which side is used longer and whether it should be replaced.
However, single-edged safety blades do not have this problem. They are not confused when they are used.

Personally, I like products with strong mechanical sense very much. I refer to the mechanical design of some folding knives,
Two locking hinges are used to make the folding razor stretch and fold freely, and the upper and lower blades are fixed by magnets.
And the main body of the product can be quickly disassembled into the original accessory state through a few screws. If there is a need for garbage classification, it should be helpful.
Thanks to the cooperative structural engineer, he made these ideas very smooth.
This product is very much like a tool knife that a ranger will carry with him, and the name of the design comes from this.

I hope I can play even a pinch role in protecting the environment ~
Finally, although the design attempt on environmental protection is likely to fall into the empty space in the end, there is a big difference between thinking and not wanting, doing and not doing, right ~
