The Single Edge SE

4135 reviews

One blade. Solid steel.

"I have been using the Single Edge SE for about three years. I will never use any other razor. Just the savings in razor blades has more than paid for the razor. The shave is wonderful. It took a few shaves to get used to the angles, and to let the razor do the work." - David G, 2026

The Supply Single Edge SE razor brings the barber's method home: the blade cuts at the skin's surface instead of dragging beneath it. This razor is designed so nothing moves or flexes: the head is fixed, the blade angle is set. You control the rest. Most men have the angle down inside five to ten shaves - and it pays you back with calmer skin that gets better every week.

Single Edge SE.
Solid zinc alloy handle, zinc alloy head. Fixed head with NickStop Safety Bar. Built to last decades. Two finishes: Classic Matte and Matte Black.

NickStop Bar.
Sixteen micro-fins along the bar regulate how much skin meets the edge. The fins make the learning curve more forgiving. Technique is still required.

Black Label Blade Pack.
Razor ships with eight injector-style blades, solid steel, twice as thick as a standard razor blade. Made in Seki City, Japan. About ninety days of shaves at eight to ten per blade. Non-proprietary. Available from Supply or other brands.

Wash your face and apply a dense shaving cream or lather.
Rest the head flat against your skin. Tilt your hand down until the blade engages with the hair. The fixed head keeps the angle for you. Shave in the direction of hair growth.
Use short, light strokes. Don’t apply pressure. The weight of the handle does the work.
Rinse the head often. Re-lather for a second pass across the grain on tolerant skin.

Most men find their pressure and stroke within five to ten shaves.

What does SE stand for?
Originally Sensitive Edition. The name stuck. The SE is the more forgiving of Supply's two razors: fixed head, NickStop micro-fins, blade slightly off the skin. More forgiving than the MAX, less forgiving than a cartridge. Razor burn comes from pressure and overdue blades.

Is a single edge razor better than a cartridge razor?
A single edge cuts cleanly at the skin's surface. Cartridges stack blades that multiply friction and drag. Most men who switch report less irritation, razor burn, and bumps, especially on the neck. The tradeoff is technique. For men willing to learn, the result is better skin and a closer shave over time.

What blades does the Supply Single Edge SE use?
Standard injector-style blades, in production for over 100 years and available from multiple brands. Supply's blades are twice as thick as standard razor blades for less flex, less drag, and a cleaner cut. Buy them from Supply or from other retailers.

How long do Supply razor blades last?
Eight to ten shaves per blade. A pack of eight lasts about three months at 5–6 shaves a week. Replace at the first sign of tugging. A sharp blade is safer than a dull one.

Is the Supply Single Edge SE good for beginners?
Yes. More forgiving than the MAX, less forgiving than a cartridge. The fixed head and NickStop micro-fins hold the blade at a consistent angle, which reduces the guesswork. Most men find their pressure and stroke within five to ten shaves. The first week is slower; the skin gets better once the technique clicks.

What is the difference between the Supply SE and the Supply MAX?
The SE has a fixed head with NickStop fins that hold the blade at a consistent angle. Supply's most forgiving razor, built for men new to single-blade shaving. The MAX has a pivoting head and exposes more of the blade at skin level for a closer shave, but requires more control. Start with the SE if you're new. The MAX is for shavers who already have the technique and are looking for the closest shave.

How much do Supply razor blades cost?
A fraction of cartridge refills. A year of Supply blades costs less than a single pack of name-brand cartridge replacements. Each blade lasts 8–10 shaves; a pack of eight covers most men for three months.

Will the Supply razor help with razor bumps and ingrown hairs?
Single-blade shaving is one of the most effective ways to reduce both. Cartridges with stacked blades cut hair below the skin surface, which causes hair to curl back and grow inward. The SE cuts at the surface with one blade. Shaving with the grain on the first pass and mapping the neck hair direction make the biggest difference. Most men see improvement within the first few weeks.

Fewer blades. Calmer skin.

Most shaving irritation comes from friction and pressure. Multi-blade cartridges stack cutting edges and drag them across the skin. That increases contact, increases pressure, and often cuts hair below the surface. The result is the irritation, redness, and ingrown hair pattern most cartridge users live with.

The Single Edge SE works differently. One blade cuts cleanly at skin level. Fewer passes. Less friction. A smoother, more controlled shave off one blade.

Single-blade shaving does require adjustment. Pressure matters. Stroke matters. Speed does not help. The SE is designed to make the learning curve more forgiving without removing responsibility from the user. Learn it on the SE - the same one-blade method barbers have used for a hundred years.

From the wet shaving authority:

"Forgiving, drama-free and very effective."

Sharpologist has covered wet shaving for over 15 years. The full Single Edge SE review is linked above, read it before you buy. There's still a learning curve: most men have the angle down inside five to ten shaves. The 30-day money-back guarantee runs longer than the curve.

Read the one-star reviews first.

4.7 stars across 4,000+ reviews. The one-stars are men who rushed it; the five-stars, men who slowed down and learned the ritual.

Some people give up after the first few shaves. Others slow down and never go back.

Most men find their pressure and stroke within five to ten shaves. The first week is slower than a cartridge. The skin gets better once the technique clicks.

If you already buy fewer, better things and take the time to maintain them, this razor was built for you.

Best razor ever! I ordered the SE because I had never tried Supply and just wanted a starter razor, turned out to be the absolute best! Highly recommend!

I’m 71 and have been shaving with a Safety razor since 14
This single edge injector razor is the smoothest shave i’ve ever had. I’ve used injector razors in the past and have a great collection of razors, shave brushes and shave bowls so i feel i know what i’m talking about when i say, Run to this website and purchase this razor

Happy to know that you are giving the SE razor a 5-star review, Tom! Thank you so much for sharing -- Truly appreciate it!

Smooth and comfortable

I haven’t used an injector razor since the late 60’s. I use a double edge razor. This gives a smoother shave than the double edge.

Glad to know that you are getting smoother shaves with the Single Edge Shave set, Terry! Truly appreciate you sharing and giving a 5-star review! Thank you so much!

Single edge, razor

The razor is very high-quality solid metal and gives a very smooth shave without irritating the skin by far the closest shave I ever had

Thank you so much Sam for the 5-star review of your Single Edge Shave set! Appreciate it!

Razor works great.

Glad to know that the SE razor works great for you, Ben! Thank you so much for the 5-star review!

Awesome Quality

Wonderful quality across the board for this shave kit. The blade is super sharp (be careful the first time you use it if you're like me and coming from always using normal 5 blade razors!) and the lather is nicely concentrated so you don't have to use much of it each time. I also love the post-shave spray - it smells great!

Awesome to hear your review, Chase! I'm so happy that you are getting wonderful shaves with your SE Starter set! Thank you so much for the 5-star review!
