Merkur - 510 Progress Adjustable Safety Razor, Bright Chrome Knob

Merkur 510 Progress Adjustable Safety Razor is the long handle version of Merkur’s classic adjustable razor, featuring a bright chrome metal knob for a clean, modern look and precise control.

Designed for those who prefer extra reach and a more substantial grip, the longer handle makes it easy to maintain a steady, comfortable hold, even with larger hands or when shaving harder-to-reach areas. With a simple twist of the chrome knob at the base, you can open or close the blade gap to fine-tune the aggression from a mild daily shave to a much closer, more efficient pass on heavier growth.

The 510 Progress combines a solid brass handle with a die-cast zinc head, finished in bright chrome for durability, corrosion resistance, and a refined, mirror-like appearance. Its two-piece construction allows quick, reliable blade changes, while the numbered adjustment scale lets you return to your preferred setting every time, making it a highly versatile choice if you like to tailor your shave to your beard length or skin sensitivity.

• Type: Two-piece, closed comb, adjustable safety razor.
• Handle length: Long handle for improved reach and control.
• Handle material: Brass handle with bright chrome metal adjustment knob.
• Head material: Die-cast zinc (Zamak) razor head with bright chrome-plated finish.
• Finish: Bright chrome throughout for a sleek, classic appearance.
• Adjustment: Twist-to-adjust design with numbered scale to change blade gap and shaving aggressiveness.
• Dimensions (razor): Approx. 4.2 cm x 2.6 cm x 10.5 cm

To use, insert a double edge blade, tighten the head fully, then dial the chrome knob to your desired setting, starting low if you have sensitive skin and increasing gradually until you find your ideal balance of comfort and closeness. The extended handle, bright chrome finish, and fully adjustable head make the Merkur 510 Progress an excellent all-rounder whether you are refining your technique or looking for a single razor that can adapt to different routines and beard types.
