Manix S110V blade broke from cutting PP board

[shqxk]

This happened to IRL friend of mine. He use the knife to cut thru some PP board and the blade just broke without even applying much pressure...

I know S110V is brittle by nature so this properly cause from some defect issue.. maybe the HT? The grain seems to be kinda rough for powdered steel tho.

The owner live in Thailand and he asked me to post here. Would appreciate any suggestion about what he should do. Thanks

I might be mistaken, but to me it looks like it was already cracked. The cardboard was just the straw that broke the camel's back.

Why do you say that?

Why do you say that?

The discoloration along one side of the fracture.

Why ruin a good story with facts?

Have you contacted spyderco? That would be my first recommendation.

He needs to contact Spyderco. It is impossible to diagnose from a distance, particularly with suboptimal pictures. The forum members here and on FB can do nothing about it, and any speculation about the cause is just that.

I've seen several pics in the past yrs of Spyderco blades which snapped at the Spydie hole...
Interesting...

Owner lives in Thailand. What are the chances it is a fake? He'd have to send it to Spyderco either way.

Never say never but I don't think I've ever seen or heard of a fake S110V Manix 2. I don't think I've even seen a fake Manix 2 that looks that close to the real ones.

I've seen Spyderco blades that break at that same spot but I find it hard to believe it broke just cutting that material. My guess is that there was a hairline crack in it beforehand

Very common to have a crack from earlier bending side pressure, then finally gives up with more normal usage.
The Spyder hole is a design we all enjoy however, it results in less material to resist bending and is the weakest area in the blade.

^This.

I've also seen other brands (e.g., ZT) of knives that had cracks on the blade near the thumstud. Anytime you drill a hole on as blade you are creating a weaker spot. For normal use and with not-so-brittle steels, these holes should not be a problem.
