Well that was a first

[JasonGotaProblem]

I got a couple rod blanks on the super cheap. Including a 9' carbon tape/graphite composite that I love the action on. Well it was super grimy so I was cleaning it with alcohol to see how much was scratches and how much was grime. Well on a downward stroke I got this splinter embedded so far into my hand I could barely grab the back of it. Almost an inch.

I was doing some test bends it seemed fine. Does this mean the blank is trash?

Tried to imagine what that felt like and quickly gave-up. OUCH!!!!
Don't know enough about rods to say, but it don't sound good...

Do a close inspection with a magnifier to see if the splinter was part of the rod or something that got stuck to it.  If the blank is dammaged I would not use it.  It is odd to have a linier flaw, most are radial.

Carbon fiber splinters suck.  Hopefully you got all of it, cause it ain't gonna break down like a wood splinter.

First off OUCH!!!  If you were rubbing with alcohol hopefully it's just something stuck in the finish that loosened up. Magnifer is a good call to see if you can find a flaw. Before wrapping it bend it and see if it brakes

You said cheap, My guess is un sanded blank .   That splinter may be from the edge of the cut flag when it was rolled .

Ouch! I've done that before on old fiberglass rods that were stripped incorrectly by myself but the size of that monster. If it was going to a personal rod I would take my chances and wrap it but I'm sure others will have differing opinions. Like I said above, I've gouged some serious chunks of fiberglass out of a rod and still have and fish them. I think a lot of people are overly cautious, probably with good reasons but I fish some rods guys would never think of using. Maybe I just don't catch big enough fish

I'm stuck at ouch!!!  Did you have another question?

I would inspect the blank as mentioned above. Do some stress flexing of the blank and see where that flaw may be located, under a guide perhaps?  That usually is when I decide to scrap that blank or use it.
