I write from memory.
Fairbairn designed two knives, and he didn't really design the first one in a design vacuum, nor the second knife.
Fairbairn received the definitive knife of this type from two US Marine Corps officers who presented it to him as gift in Shanghai, where they served together.
The two Marine officers had the knife made by the Shanghai police department armorer, and the armorer had a good idea what Fairbairn would like.
The
Pattern One corresponds to the knife Fairbairn and Sykes presented to Wilkinson for manufacture.
This knife differs dramatically from the Pattern Two and Pattern Three knives later made by Wilkinson, in that it has an unsharpened "tablet."
Wilkinson changed Fairbairn's design without permission in order to facilitate the manufacturing process.
I believe when Fairbairn saw how well the knife sold, even with the modification, he kept his mouth shut and took the royalty checks.
Later in the war, Fairbairn designed a second knife, the
X Dagger.
This knife also has an unsharpened portion, although not a distinct "tablet" as on the Pattern One.
Nonetheless, I believe the unsharpened portions of both the Pattern One and the X Dagger represent Fairbairn's actual intent.
If one handles either the Pattern Two or the Pattern Three knives, one might consider the handle rather small.
I believe Fairbairn meant for the user to hold the Pattern One and the X Dagger with the index finger wrapped around the unsharpened portion of the blade, and with the hilt otherwise serving as a subhilt.
Make a fist.
Stick the thumb straight up and the index finger straight out, as if pointing a gun with the thumb serving as the hammer.
Take a pen or a pencil and lay it on top of the clenched middle finger and across the web of the thumb.
Wrap the index finger over the pen and the thumb over the index finger.
Think of the pen as the hilt of the knife.
I think Fairbairn intended this knife as a desperation knife that would fall instinctively to hand and which would not come out of the hand as long as the user remained conscious.
Early in his Shanghai career, Fairbairn received a terrible beating on the street, probably intended to kill him.
He had a six month hospital recovery.
When he got out of the hospital, he studied Judo and recieved his second degree Black Belt from Jigaro Kano himself.
He also started carrying a knife very much like the Pattern One, and had it on his person at all times.
A knife held in the manner I described above will counter a wrist grab and the hand will not slide up or down the knife, no matter what happens.
No matter what happens.
The FS Pattern Two received its reputation for a fragile tip because the American manufacturers who supplied this knife to the early American Marine Raiders did not use the steel Wilkinson specified nor did they follow Wilkinson's prescribed heat treatment.
The Marines broke the tips off of these knives so frequently the Marines eventually rejected them.
In contrast, the knives made by Wilkinson and Wilkinson subcontractors, and as issued in the European theater, did not break.
The Pattern One and the X Dagger, as presently made by Brent Sandow for NZ Knives, have no equal.
They will not break and they correspond to Fairbairn's intent.
The last I heard, NZ Knives would not ship these knives in a sharpened condition.
If that remains their policy, I would have mine sharpened by a professional knifemaker so as to not scratch the finish nor undo the heat treatment by overheating the steel on a wheel.
