Alright, let me tell you about this new-ish gadget I’ve had the chance to play around with – the Supply Trimmer. As someone who’s used a fair few grooming tools in my time, and having been familiar with Supply’s reputation for their single-edge razors, I was definitely intrigued when they launched this new product. So I bought one to put through its paces.
My Experience With The Supply Trimmer

Overall, my impressions of the Supply Trimmer are quite positive. It feels well-built, is easy to use with its single-button operation, and excels at what it’s primarily designed for: precise trimming and shaping of facial hair (or body hair).
When it comes to using it, the main thing that Supply seems to be pushing, and what I’ve found to be the case as well, is its precision trimming capabilities. Many shavers who shape facial hair struggle with getting clean lines and consistent lengths using traditional electric razors. Those wider heads can be clunky and make it easy to accidentally take off more than you intended. Even with older dedicated trimmers, like my ancient Norelco, the guards would sometimes slip, leading to uneven results. The Supply Trimmer feels different. That narrower head and the adjustable comb give you a lot more control. I can definitely see this being ideal for shaping sideburns, tidying up around a mustache, or getting that crisp edge on a beard or goatee. Someone who likes to get creative with their facial hair or keep it meticulously groomed would likely find this tool very appealing.
While the emphasis is on trimming, the Supply Trimmer can also be used for a complete shave. I have used it for a full face shave more than once when I’m in a super hurry and it does a decent job, especially under the nose where the narrower head is a real advantage. It’s a quick and easy way to get rid of stubble, sort of like using an electric razor flat against your skin. However, because of the thickness of the head, it probably won’t get you that super close, baby’s-butt-smooth shave that some people prefer and that you can often achieve with traditional wet shaving methods.

So, while it’s capable of a full shave, I think its real strength lies in its trimming prowess.
First off, let’s talk about what you get. The trimmer comes in a pretty straightforward box, nothing too fancy, but it does the job of protecting what’s inside. Opening it up, the first thing that caught my eye was the trimmer itself. It feels really solid in the hand, a nice weight to it that suggests quality. Along with the trimmer, you get an adjustable height comb, which seems quite robust and has these little micro adjustments that look promising for getting just the right beard length.
There’s also a charging station with a proper plug – a welcome change from some companies that just give you a USB cable and expect you to have a brick laying around. Supply also includes a USB-C charging cord, which is modern and convenient, and even a little blade guard or travel cover for the head. I also appreciated the little note from the folks at Supply asking for my honest opinion – a nice personal touch.
After charging and in use I found the Supply trimmer to run noticeably quieter, longer, and cooler than the Oneblade per charge, with better ergonomics.
Design
The build quality feels solid, with no loose parts that give me any immediate concerns about durability. The head is also easily removable for cleaning. Battery life seems very good too, with a full charge giving me at least 90 minutes of use. The charging base is convenient; you just drop the trimmer in, and a little light indicates that it’s charging – a nice touch.
The design of the trimmer itself is quite interesting. It’s got this sort of faceted look to the body, which makes it stand out a bit. It’s not just about looks though; it feels good to hold. The head of the trimmer features a dual-edge micro blade and a pivoting mechanism. I have found the pivot is really useful for following the contours of the skin. There’s also a handy little light built into the trimmer, which might be useful for getting a better view of what you’re trimming, especially in those tricky spots.
The adjustable comb attaches easily with a notch and catch system, and you can dial in your desired hair length. The range goes from “1” to “9.5” (though I’m not entirely sure what those units correspond to). It feels secure once attached, with no obvious flimsy parts that look like they might break easily.
It’s worth noting that the Supply Trimmer is also waterproof, which is a great feature for easy cleaning under the tap or using it in the shower.
Supply Vs. Phillips Oneblade?

The business end of the Supply Trimmer bears a resemblance to the Philips Norelco OneBlade (not to be confused with the OneBlade safety razor!). I have had a Phillips OneBlade for years (first generation) so it makes sense to talk about how these two products stack up against one another. Both sport a similar head design and are designed for trimming but can handle a full shave in a pinch. But there are some key differences.
One thing I appreciate about the Supply Trimmer was the inclusion of a proper charging stand and a wall plug. The Phillips OneBlade I have has a non-standard charging cable/plug. I have found that as an electric trimmer/shaver head heats up with continuous use it becomes less effective.
It is worth noting that there are now several variations of the Phillips OneBlade, including an “Intimate” groomer and a “360 Pro Face & Body Trimmer” (that might be a little more of a direct comparison to the Supply Trimmer in terms of features).
While both did a good job of trimming, I initially found the OneBlade’s trimming head adjustment a little less intuitive than the Supply’s, but both worked well. Ultimately, both seem to be decent options, and the choice might come down to personal preference regarding the pivoting head, the included accessories, and perhaps the long-term cost and availability of replacement blades.
Summing Up
While the Supply Trimmer can handle a full shave, I think those looking for the absolute closest shave would still prefer traditional methods. However, for maintaining a beard or goatee at a specific length, or for achieving defined lines and styles, I think this trimmer is a very capable tool. The inclusion of a proper charging stand and the overall design are definite pluses. Based on my experience, if you’re serious about keeping your facial hair looking sharp and precise, the Supply Trimmer is definitely worth considering.
