Overview
Wet shavers with sensitive skin or coarse stubble get a double edge razor whose blade gap changes with a twist of the handle. The two piece Merkur Progress loads a standard blade into a closed comb head on a long brass handle with a chrome finish.
Adjustability is the reason to choose this razor: a gentle setting for the neck and a closer one for the cheeks from the same tool. The heft of brass lets the razor's weight do the cutting without pressing. Blades are not mentioned among the contents, so buy a pack separately.
Who it's for
Made for a daily wet shaver with larger hands who wants one razor that adapts from a mild pass to a close one. Those who prefer pivoting multi blade cartridges or a feather light handle will find it unfamiliar.
Pros and cons
- Blade gap adjusts by twisting the handle
- Takes any standard double edge blade
- Long brass handle suits larger hands
- Plastic free build
- Blades not listed as included
- Adjustment takes trial and error to learn
- Heavier than aluminum or plastic razors
Performance notes
Shave aggressiveness is governed by the blade gap, which the handle dial widens or narrows. A wider gap cuts closer on coarse stubble, a narrower one is milder on sensitive skin. The brass weight supplies the cutting force, so the maker advises no added pressure, a shallow angle and shaving with the grain.

Frequently asked questions
How do you load a blade in the Merkur Progress 510?
The Progress uses a 2-piece design that the maker says makes loading blades simple. The listing does not spell out the steps, so follow the maker's directions.
What angle should I hold the Merkur 510 at?
About a 30-degree angle, per the description. Let the razor's weight do the work and shave with the grain.
Can I change the setting mid shave on the Merkur 510?
Yes. Twisting the handle changes the blade gap, and the description suggests a gentler setting for sensitive areas such as the neck.
Is the Merkur 510 a cartridge razor?
No. It takes a single standard double edge blade, with no custom cartridges or subscriptions needed.
