Just about any knife can cut string or trim a coupon out of
the paper. But let’s get down to
specifics. There are knives designed
solely for self-defense. Not knife
dueling, like Tommy Lee Jones and Steven Seagal in “Under Siege,” but an honest
to Gawd cut-them-off-of-me defense.
The three I have in mind are Ka-Bar’s TDI knife, Shadow Tech’s
QRT and TOPS California Cobra.
The first thing you notice is they’re all fixed blades. Despite what you think or practice, rolling
around and fighting for your life makes it difficult, almost impossible, to
produce a folder, get it open and use it.
It takes practice. A lot of
practice. A fixed blade makes that
aspect so much easier.
The TDI knife is well known.
John Benner designed a knife that police could carry behind their
magazine pouch. The curved shape lets
you stab and slice with the wrist in the neutral position. This is a powerful position as the cutting
edge is parallel to the long bones of the arm.

Ka Bar's TDI Knife |
It’s made in Taiwan but it’s a Ka-Bar so you know the quality is built
in. The curve and oval handle keeps the
blade centered in your hand and prevents you from sliding forward on the
knife.
|
The reverse grip has become popular. Weak-side carry, draw the knife with weak-side hand, slice your way free. |
It’s never a good idea to cut
yourself when the chips are on the line.
It also works very nicely in a reverse grip. Just drag your fist over anything that’s not
you and it is cut.
I picked up Shadow Tech’s QRT at this year’s Blade
Show.

Shadow Tech QRT. That's Quick Response Tactics to you. |
They were still smoothing out a
few of the wrinkles but I recognized it’s coolness from a distance. I only had to hold it to realize its
potential.
The Bowie style blade is
almost perpendicular to the handle.
Again the wrist can stay in the neutral position and not be hyper-extended
in the saber grip. Hyper-extension of
the wrist robs strength from the fingers.
The oversize hole really gives you an almost unbreakable
grip and the coarse jimping on the top provides plenty of grip surface for the
thumb. It’s another knife you won’t slide
onto the blade if you stab into something hard.
|
Trust me, this knife isn't going anywhere I don't want it to go. |
Unfortunately the hole is too small for my hands in winter gloves. There’s a little choil under the ring that
can be utilized by the gloved index finger.
It’s right next to the blade so be careful and hope that between the
glove and the handle jammed against the palm of your hand you will not get cut. It’s a poor knife that only cuts one way, so a
reverse grip can be utilized. Again,
just practice and learn to cut anything that’s not you.
TOPS California Cobra is a nasty little piece of work. Oh, it’s quality and I’m sure it works just
like they claim, but one look at it would be enough to discourage me.
|
TOPS Cobra. It almost hurts you to look at it. |
The knife has three useful edges. Useful to you that is, not the target. One is a sharpened pyramid at the bottom of
the guard. TOPS calls it the sting, the
less lethal option.
|
Sharpened Steel Sting Get the point? |
I can imagine
jabbing someone with it and convincing them they should let go and find someone
else to hurt. Both blades are
referred to as the fang, or more lethal part of the knife.
Both blades?
Yes. It’s a bent
dagger.
The knife comes with an over-xeroxed booklet called the
“Dirty Dozen and Then Some.” The booklet
shows you several self-defense techniques with the knife. The normal grip for the Cobra is a saber grip
and to bring the blades to play, you need some degree of hyper-extension.
|
Be careful where you move your thumb to! |
The Cobra, like almost all knives including
the TDI and the QRT, can be held in a reverse grip. In the reverse grip your wrist is in the
neutral position.
Does the hyper-extension wash the Cobra out? Nope, but it’s a consideration. Another consideration is the fact that your
thumb can slide onto the top blade if you extend it too far. On the plus side the handle has sufficient
distance from the blade to accommodate heavy winter gloves.
The cobra doesn’t look like a knife in its
sheath, a feature it shares with the TDI knife.
I find this to be valuable asset when I wear one in public.

I left the price blank.
If you shop around, you should be able to find a deal on any of these
three.
My last impressions.
These knives target (if you pardon my expression) the police
market. The uniform and gun make police
a target of opportunity. Criminals know
there is a gun present and exactly where it is. Holding a bad person at gunpoint, an
officer could be jumped by anyone from the guy's mother to his baby sister. These same problems may apply to the armed
civilian. Having a fixed blade could
make all the difference between regaining control and being found dead on the
side of the road.
We throw a blanket statement of “It’s a tool, just a tool,”
over any knife we carry. I think you
might find it difficult to explain to a jury what kind of tool the Cobra is. It looks so wicked and excessively punishing
you better have good reasons you can verbally and convincingly express.
I like the raw look to the QRT. I think the blade needs a little
polishing. There’s a balance between so sharp
it has a brittle edge and being robustly dull.
I think my QRT was a little too robustly dull. I polished the edge a
little and I’m quite happy with its cutting ability.
The TDI knife is the
standard by which all weapon retention tools are measured against. It’s well made and has a refined
elegance. It doesn’t look menacing,
doesn’t look dangerous and it’s likely it will not be noticed until it’s
performing its designed function. It’s
my first choice, but I have sentimental reasons to like it.
