Are titanium-coated Navimow blades better than OEM?

Not in our testing. We ran both sets on the same mower and measured them fresh and after a month of mowing. The OEM Segway blades read sharper on a laser edge reader out of the package, weighed about 25% more (2.5 oz vs 2.0 oz per 20 blades — more actual steel), and after equal run time the worn OEM blade still showed a defined edge while the worn titanium blade barely returned a reading.

Are titanium Navimow blades actually made of titanium?

No. They're stainless steel with a very thin titanium nitride (TiN) coating — the same gold finish used on inexpensive drill bits. At the cutting apex, which is thinner than the coating itself, that layer wears through almost immediately, and after that you're cutting on the base steel. In the set we tested, that base steel was both lighter and duller than OEM.

How much do Navimow blades weigh?

Individual blades are too light for a normal postal scale, so we weighed them 20 at a time: 20 OEM Segway blades came to 2.5 oz (~71 g, about 3.5 g per blade) versus 2.0 oz (~57 g, about 2.8 g per blade) for the titanium-coated set. Heavier means thicker stainless — more resistance to bending and edge rounding.

How long do Navimow blades stay sharp?

In this test, neither set could cleanly cut a single blade of grass after about 30 days of regular mowing — coated or not. That's why we tell customers the replacement interval matters far more than the blade brand: plan on a fresh set every 4–6 weeks with daily mowing, with new screws every time.

“Titanium” Navimow Blades vs OEM: We Tested Both — OEM Won

If you own a Segway Navimow, you’ve seen the listings: gold-colored “titanium-coated stainless steel” blades, a few dollars cheaper than the OEM set, promising a longer life and a sharper cut. Back in July we laid out our honest expectations and predicted a modest gain at best.

We were too generous. We ran both sets side by side on our own Navimow for a month, then measured everything. The stock Segway blades won every check we ran — sharpness, weight, and edge condition after equal run time.

The full test is in the video above. Here’s what we measured and what it means for your mower.

How did we test the blades?

Three checks, same mower, same lawn:

Edge sharpness on a laser edge reader — a bench tool that projects the blade’s bevel onto a scale, so you’re reading the edge itself instead of guessing with a fingernail.
Weight on a scale, because on a stamped blade, weight tells you how much stainless steel is actually there.
Real cutting — a fresh and a 30-day-old blade from each set, cutting paper and individual blades of grass.

One honesty note before the numbers: the edge reader is an estimating tool, not lab metrology, and the cutting checks are a feel test. We’re a dealer and service center, not a materials lab. But the results all pointed the same direction, and the direction was not close.

Which blades are sharper?

The OEM Segway blades — fresh out of the package and again after a month of mowing.

On the edge reader, the brand-new titanium-coated blade showed its bevel at roughly the 12 mark on the scale. The brand-new Segway blade projected a visibly tighter, more defined edge — sharper than the coated blade before either had touched grass. So much for the “sharper cut” on the listing.

The month-old blades told the more interesting story. The worn Segway blade still showed a recognizable bevel — rounded and diffused, clearly due for replacement, but present. The worn titanium blade barely returned a reading at all. Its edge was simply gone. Look at it in the video: after the same run time, the gold blade is discolored, worn through along the edge, and rusting where the coating flaked — which tells you exactly how thick that coating was.

Which blades are heavier?

OEM, by about 25%. Individual blades are too light for a postal scale to register — we tried — so we weighed them in batches of 20:

Blade set (20 blades)	Weight	Per blade
OEM Segway Navimow	2.5 oz (~71 g)	~3.5 g
Titanium-coated aftermarket	2.0 oz (~57 g)	~2.8 g

You can feel the difference in your hand before the scale confirms it. Heavier means thicker stainless steel, and thicker steel holds an edge longer, resists bending when it clips a root or a pine cone, and keeps the cutting disc balanced. The aftermarket blades are lighter for the least flattering reason possible: there’s less metal in them.

What does “titanium-coated” actually mean?

The blade isn’t titanium. It’s ordinary stainless steel with a titanium nitride (TiN) coating a few microns thick — the same gold finish you see on cheap drill bits.

On a drill bit spinning in a controlled hole, TiN genuinely reduces friction and heat. On a mower blade slapping through wet grass, sand, and the occasional stick, the story is different: the cutting apex is thinner than the coating itself, so the edge wears through to bare steel almost immediately. From that point on, the base steel is doing all the work — and in this set, the base steel is thinner and duller than what Segway ships.

It’s marketing, not engineering. The gold color is doing the selling.

How did they cut real grass?

Fresh against fresh, both cut — the new Segway blade sliced a slightly cleaner line through paper, while the new coated blade tore a little. Grass told the same story: both new blades snipped individual grass blades cleanly.

The result that should change your maintenance habits came from the worn sets: after about 30 days on the mower, neither blade — coated or OEM — could cleanly cut a single blade of grass. Both tore instead of slicing.

That’s the real lesson hiding in this test. The difference between a fresh blade and a month-old blade is enormous; the difference between blade brands is small. If your lawn looks slightly gray-brown a few days after mowing, it’s your blades, not your mower — and no coating will save you from the calendar.

The verdict: which blades should you buy?

Buy the OEM Segway Navimow blades. They measured sharper new, sharper worn, and roughly 25% heavier-duty, and the price difference against the aftermarket set is a couple of dollars across an entire season. There is no version of this math where the coated blades win.

Then spend your attention where it actually pays: replace on schedule, with new screws, every time. Even a genuinely longer-lasting blade wouldn’t help you much — the pivot screws wear out on their own interval, and they’re the part that actually fails. We also stock complete cutting discs with fresh OEM blades pre-installed and torqued correctly — they’ve been selling out as fast as we can build them, but new shipments land every week. Ask us.

And one more thing from the video: the best blade upgrade for a Navimow isn’t a different blade — it’s more of them. We’re about to show how to go from 6 to 9 blades per disc, safely and balanced, for about 33% more cutting edge. Subscribe to the channel or check back here for that one.
