Spartan Blades LLC proudly make "Knives with Intent", and their Pallas Button Lock folder is no exception, fulfilling its design brief exceptionally well.
The Blade and Handle Geometry:
Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.
Using a set of gauges and precision measuring equipment including a Vernier protractor, callipers, fixed radius gauges and the unique Arc Master adjustable radius gauge (the one that looks like a crossbow).
These measurements have been tabulated and are presented along with a few reference blades (8" Chef's Knife, 5.5" Santoku and the popular Fällkniven F1).
Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.
The 'Balance relative to the front of the handle' tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The 'Balance relative to the centre of the handle' indicates how close to a 'neutral balance' the knife has in the hand.
In the case of full convex grinds the approximate centre of the grind is used for the primary bevel angle estimate.
The blade is made from S35VN steel.
Explained by the Maker:
The reasons for certain design choices may not be clear when simply looking at an object, so this section is intended to give an insight into the thinking behind a design by speaking to the designer themselves.
Unfortunately I cant always get time with the designer so will use this section to include relevant information about the knife and its designer.
Mark Carey (co-founder of Spartan Blades LLC) and I discussed the Pallas at IWA 2016, so I was able to find out a little of the thought processes that brought the Pallas folder into Spartan Blades' line up.
The knife was actually designed by Spartan Blades' other founder Curtis Iovito ....
For this section, please go to the Exclusive Content at Tactical Reviews , but remember to return to this forum to discuss the review.
A few more details:
The Pallas box along with a Heinnie Haynes sticker to signify the creation of this 'UK' Version of the knife.
Flipping open the box, and the Pallas is sandwiched between foam liners with a Spartan Blades sticker included.
Fresh out of the box, the Pallas.
Straight in for a look at three key aspects of this knife, it is made by Spartan Blades (with the logo engraved in the handle), there is a button lock, and the blade is S35VN steel.
Closer still to the stainless steel button.
Despite an overall flat cross-section, the Pallas is full of curves that make the design flow and provide its ergonomics.
Note the deviation from a standard Pallas in the there is no longer a flipper tab on this special UK version.
SpartanBlades' signature titanium arrow pocket clip.
The pocket clip is one sided and cannot be fitted to the side with the lock button.
This is where the flipper tab would be on the standard Pallas.
Button locks are far less common in non-autos, than other locking mechanism, so warrants a closer look. Here the blade has been opened slightly to allow the button and its shaft to be seen.
Viewed from a slightly higher angle you can see how the button has been pulled into the handle as the blade starts to open.
With the blade a little further open you can see the locking notch in the blade into which the button engages. You can see it is just to the right of the blade stop pin.
The blade is now nearly fully open and the locking notch has nearly reached the button.
And fully open the button has locked itself into the notch in the blade. The blade has also hit the stop pin and is firmly wedged between the two.
Now the blade is fully open, the UK version trimmed off flipper tab can be seen more clearly.
The overall view.
when looking closely at the blade tip you can see the contrast of the crispness of the final edge bevel and the rounded blade spine.
The entire blade surface has a stonewashed finish.
Not quite a full flat grind, the Pallas blade is a high flat grind.
Each side of the pivot bolt is different, with a nut on this side.
And a torx bolt head on the other side.
Though they look good, the handle spacers are also a very practical design with wide flats where they contact the handles and a slight waist which will reduce weight without any significant loss of strength.
You can see straight through the handle with the three spacers one end,and the blade pivot at the other.
All the edges of the spine are nicely rounded. So you won't be striking sparks off fire-rods, but you also won't be fraying your pockets.
There is a little jimping for your thumb where the blade meets the handle.
Each side of the spacers are held with torx bolts, as is the pocket clip.
Blade centring is spot on.
When the blade is between one third and two thirds open you can see the blade-stop hook in the tang of the blade.
The cutting edge is terminated in a choil, and the plunge line is nicely radiused to reduce stress concentrators.
At the butt of the knife handle, there is jimping top and bottom giving a surprisingly useful amount of grip. I'd also take this opportunity to point out the surface texture of the anodised handles. There is a matt finish to the anodising due to what appears to be an underlying bead blasted surface.
Grooves cut into this side of the handle provide grip where your finger tips press onto the handle. Subtle and effective.
The lanyard hole goes through both handle slabs.
Lastly for this section, a close-up of the thumb stud which looks crisp and precise, yet without any sharp edges on the thumb contact surface.
