What the source is: the Clear Roads “Product Experience Feedback 2006-2021” file. Why it matters: ceramic-insert blades are sometimes proposed as an alternative to carbide, and the file holds few but telling comments. I read the relevant pages on 24 October 2026. There are only a handful of entries, from different years, and the comments are opinions, so this does not settle the question of ceramics. I name a maker only because the file does.
What the file says
The file is a set of operator comments, and the wording is the evidence.
- North Dakota: the ceramic “was not durable and shattered and failed very quickly”, there was heavy drag due to the rubber encasement, and all were replaced with another blade with improved results. It rated overall satisfaction 1.
- Illinois (2008-2009): one blade tested; the comment says the product does not hold up to its snow plowing environment and needs curb guard capability, while also noting less noise, a smoother ride and that it scrapes better. Overall rating 1.
- Iowa: a comment filed under a different blade page says that in short testing the ceramic blades appeared to give longer blade life than a comparison carbide blade on micro-surface roads.
Why the reports look mixed
The reports look contradictory until you separate trial size, conditions and failure mode.
- Few trials: two entries have a quantity of one or not stated.
- Different conditions: a micro-surface road is not the same test as curb-lined urban streets.
- Impact: shattering and curb contact comments point to brittleness under impact, which the comments describe in the field, not in a lab.
- Different priorities: some operators valued noise and smoothness, others cared about durability.
Checks before you trial one
| Check | Why |
|---|---|
| Route features: curbs, covers, joints, markers | Impact is where ceramic comments were negative |
| Surface type | Smooth micro-surface produced the positive Iowa comment |
| Protection at the ends | Illinois asked for curb guard capability |
| Trial size and records | One blade says little; use matched trucks |
| Supplier support | Ask what they do if inserts fail |
What this does not tell you
- No wear-rate or cost-per-hour data is in these entries.
- Products and designs may have changed since these entries.
Boundary: Only a few state entries exist in the file and they are opinions, not controlled trials; designs may have changed since, and no wear or cost data are given.
