Cold Steel

Cold Steel describes this item as follows:

As the saying goes, "the pen is mightier than the sword." Indeed, Cold Steel makes some mighty strong swords, but this little pen makes for some clever competition. It's the biggest, baddest, permanent marker around!

Superficially, it shares many features common to most markers, but appearances can be deceptive. For starters, it's made from the glass-reinforced plastic, Grivory, the same tough material we use in our NIGHTSHADE SERIES, and features walls that are 4 times thicker than similar markers. This means it's built for impact and, in a self-defense emergency it can become an efficient Yawara stick for driving off an attacker. Plus, the screw-top cap will stay in place and won't pop off like a regular marker's cap would when you strike a percussion blow, or when obtaining joint locks or submission holds.

It's easy to carry too. Just clip it to a shirt or coat pocket, or carry in your purse, pack or brief case. Don't spend another day without one!

Pros: Materials, Overall Quality
Cons: None
Big. Very big..
This pen is what it claims to be. Very big. In my mind to big for carrying, not comfortable to write with, but if you need an item for defense purposes I am sure it will be handy. As most Cold Steel products, it delivers good value for money. I keep it in a range bag. The size makes it handy if I need a pen using gloves.

Superb self-defense capabilities.
I didn't buy these (I bought 3) to write with, but as a low profile self-defense instrument. They are just the right size for me, as I have large hands. Perfect fit. Solid. Hard. I feel better armed with one of these than with a kubotan. Nothing to explain to anyone either. Nothing to break down, nothing to rust. ROCK-solid. Sure, you can buy a "tactical" pen for 10 times (or more) the price, but I don't see why.

Cons: Refill Quality, None
Good for a tool, too large to use as a writing utensil.
