Learn when to replace your trimmer blade, how to install a pack of 2 refills, and simple maintenance tips to keep your Supply Trimmer cutting cleanly.
Quick answer
Replace your trimmer blade every 3–4 months, or sooner if you notice pulling, uneven trimming, or a dull edge. The Trimmer Blade Refill - Pack of 2 gives you a full replacement cycle, and swapping blades takes just a few minutes with no special tools.
Why blade replacement matters for your trimmer
A dull blade doesn't just cut poorly—it pulls hair, causes uneven lines, and makes you go over the same spot repeatedly, which can irritate your skin. The Trimmer Blade Refill - Pack of 2 is designed to keep your Supply Trimmer performing at its best. Each refill is precision-engineered for a consistent, clean trim every time. The manufacturer recommends replacing the blade every 3–4 months, depending on how often you trim.
Signs it's time for a new blade
Don't rely on the calendar alone. Your trimming habits and hair type affect blade life. Watch for these signals that your blade is past its prime:
- The trimmer pulls or snags instead of cutting smoothly.
- You need multiple passes to get an even line.
- The blade looks discolored or has visible buildup that won't rinse away.
- You've been using the same blade for more than four months.
How to replace the blade on your Supply Trimmer
The Supply Trimmer uses a dual-edge MicroBlade that's designed to be user-replaceable. Here's the straightforward process. Note: if your trimmer model differs, check the manual—this guide covers the standard Supply Trimmer.
Step-by-step blade replacement
- Power off and remove the blade guard: Turn off the trimmer and slide off any guard or attachment. Rinse the blade under warm water to remove loose hair. Checkpoint: never handle the blade while the trimmer is on.
- Release the old blade: Locate the blade release mechanism (usually a small tab or button). Press or slide it to detach the blade cartridge. Common mistake: forcing the blade off can damage the trimmer head.
- Insert the new refill: Align the new blade with the trimmer head and press until it clicks into place. The dual-edge MicroBlade should sit flush. Checkpoint: give a gentle tug to confirm it's secure.
- Test and reset: Turn on the trimmer and listen for a smooth hum. If it sounds strained, remove and reseat the blade. Next step: rinse the blade after each use to maintain performance.
