Yup! Here is the Sharpie T.E.C. pen.

BW also says: " Marking pens are fine to use on ropes as long as they are water based laundry markers. Years ago solvent based markers were the norm. Some of the solvents used in these old pens could reduce the strength of the sheath strands marked. These days most pens are water based so this is not as much of an issue as in years passed. We recommend a Sharpie “rub a dub” laundry marking pen."

That was Kolin Powick's point (the engineer from BD in the article). You'd be taking a 60m whipper.

I always use Dullee brand markers, because Sharpies are way too sharp.

I get the top of page 2.

IMO rope manufacturers need to be marking the middle of their ropes better so that this discussion doesn't need to occure! The bi-color is great but not all companies make it and many of the factory middle marks fade rather quickly. Seems silly that we can spend hundreds of dollars on a rope and have to mark the middle ourselves with a pen...

They mark it just fine

In fact its better thay they leave the mark off IMO ... Personally i prefer to mark it myself after verifying ita actually correct ... There been MPers who found the mark or pattern change on their ropes to be off

Not to mention if you chop a rope youll need to remark the middle

Just pick up a laundry sharpie (or beal rope marker) and mark it yourself

Thats all there is to it

;)

I wish they would mark the rope in a color other than black. Its kind of hard to see my rope's middle mark because of all the aluminum oxide on it. I guess I just need to wash my rope again.

Yeah, All of that

I prefer MY middle mark, its correct to my rope, and more visible. I use a stripe pattern that's always discernible from other dirty/ wet spots or whatever and is actually more easily noticed than a solid black patch that has faded some.

Rope companies do not use a special marker. Petzl advocates for the Sharpie brand as well. Not a problem!

Haha. I tried that with the stupid X4 thread and MP admins changed it back. Dastardly fools!

FACT: Middle marking your rope with Sharpie actually makes your rope close to 5% stronger.

The Data from the BD article:

Sample:
Peak Value (lbf)
Failure Mode

No Center Mark 2222
Rope at Bottom Knot

Factory Center Mark 2226
Rope at Bottom Knot

Sharpie Center Mark 1 2311
Rope at Bottom Knot

Sharpie Center Mark 2 2334
Rope at Bottom Knot

Sharpie makes your rope stronger, case closed.

I dropped my sharpie. Should I replace it because microfractures?

Microfractures actually make your sharpie stronger.

So I marked the middle of my rope with a sharpie which makes it stronger. But I also dropped my rope so I'm worried about the microfractures. Do these phenomomena cancel each other out??? Someone help!!

Lol glad I could get a good laugh in today

So does this mean I should sharpie my entire rope so it'll be stronger?

thanks for the info! I just covered my cams, nuts and ice screws with a black sharpie! I`m ubber safe now! About to buy a case to cover my crash pad!

I'll give you a big +1 for straying from the time honoured "send it to me for disposal."
