Knife Review: ZT450CF

Ah…Belarus, a small Eastern European landlocked country best known for its Stalinist architecture and grand fortifications.  If you’re stopping for a tour, make sure you visit KGB Headquarters looming over Independence Square and the many Great Patriotic War monuments commemorating the country’s role in WWII.

Sounds bleak, doesn’t?  Especially the tour of KBG headquarters which could last 20 to 30 years.

I really like the carbon fiber handle.

From this country comes Dmitry Sinkevich, knife maker and artist.  His knife designs are snapped up by companies like Spyderco and Zero Tolerance.  It only takes a simple look to see why.

Let’s look at his design, the ZT 450CF for example.  The knife sports a 3.25 inch slice of CPM S35VN.  More on this steel later.  The blade is a saber grind, drop point with a long false edge and flipper.  The blade glides open on KVT ball bearings.  The front of the handle is carbon fiber and backed with titanium.

The clip is reversible and provides a relatively low profile look when pocketed.

This makes for a very trim and graceful knife weighing in at 2.45 ounces. 

The lock mechanism is a standard frame lock, but because titanium can’t be hardened to the same values as steel, the locking bar sports a small steel insert that serves two functions in addition to locking the knife open.  One, it takes the wear of contacting the steel blade and two, acts as a stop to prevent the bar from being pushed out beyond its elastic limits.  The insert, in case you were wondering, is replaceable.

The carbon fiber is striking.  This is a very nice Gent's Knife.

S35VN is martensitic steel which contains 3% vanadium and 0.5% niobium in addition to chromium.  All three elements are carbide formers, but chemical properties favor the formation of vanadium and niobium carbides over chromium.  These two carbides are harder and finer in size than chromium carbide and reinforce the steel more. 

Tests by CPM indicate the steel has better edge retention, less wear and more corrosion resistance than many steels including 440C and D2. 

I like the open back and the green spacers are just for fun and very cool.

The knife is strikingly impressive in my opinion.  It fits my hand and the blade flicks out on the KVT ball bearing.  The knife is set up for tip-up carry and the clip is reversible for left or right carry.

I can’t take it for a test run, as it’s not mine to use.  If ZT would like to send me a writer’s sample, I’ll run some cutting tests and expand this. 

The Sinkevich ZT450CF is light, trim and comfortable to use knife which is, bladed with a techno steel to give you long life and edge retention.  Frankly, at the retail price of $245 it looks like a bargain.

Provoke

A recent episode of the “The Rookie’ shows one of the characters showing his last resort knife to his training officer.  It resembles a Benchmade 175BK push dagger.  It’s a short story arc that helps support the longer main arc.   

Still, one can see why real LEOs will carry a last resort weapon.  They don’t have a room of script magicians to write them out of the problem.  These weapons are usually very simple to use.  Any tool that requires year to learn and five years to master will fall outside the definition of ‘tool-of-last-resort.’

Karambits have this tool potential.  The ordinary user can slip his little finger onto the loop and hold it in a hammer fist and simply claw his way out of danger trouble.  Placing your thumb on the back of curved spine will give you a little more feedback.  Are we not trained to touching things with our thumb?  The same almost autonomic reflex helps guide the blade.

Held in the reverse grip, the blade juts out of our fist like a prehistoric claw, perfectly situated for close infighting moves. Small wonder folding karambits are so popular.  Closed, they are easy to conceal, a basic impact weapon and open, it becomes so much more.

In the hands of someone with more training than I, the karambit has multiple applications.  The dull spine can be used use to trap and control opponent’s arms and balance, making a range of other physical responses available.  The razor edge lets you transition from physical control to higher levels of force almost instinctively. 

Folding karambits have some problems.  Opening isn’t always easy and fingers can get in the way of the edge.  Lock and pivot points wear and fail from applying load on the spine or side of the blade.  All knives direct the load into the handle but the twisting load generated by using the blade as a control device can cause handle failures.

CRKT's Provoke, designed for LEO and people in dangerous places

Many of the devices used to open the blade as you remove it from your pocket don’t assist you opening the karambit if you are holding it in your hand as an impact tool.

CRKT has taken Joe Caswell’s design and produced the Provoke.  It is a unique knife that may change how we open and close folding knives.  Your fingers are never in the path of the blade when opening or closing.  The blade is firmly locked in place by two stout arms.

The problem is opening from the pocket draw.  The optimal opening has the index finger through the ring and the dull spine against the palm of your hand.  The thumb presses the back pivot point and the blade pops open.

Back side of the Provoke.  The clip holds the knife deep in the pocket.  What you see doesn't look like a clip.

Here’s a right and left hand draw with opening showing the finger movements I use.  It looks clumsy when shone slowly to reveal finger movement.  It’s not.  Practice for ten minutes and it will feel completely natural to you.

Left side opening.  I needed to pivot out of the camera view to show the opening.  You really don't hold it like a soiled tea bag. 

Right side opening.  The knife must slide from the thumb to the index finger

It’s not an inexpensive knife and has limited general application.  Its cutting edge design and manufacturing has built in a high degree of reliability.  It is last-chance-tool to claw your way out from under the casket lid.
