..While I throughly appreciate your comments and passion, I disagree with you just as throughly.
I've made a bit of a study of these F/S knives, including ownership of said, and extensive research of its history. After many thousands of dollars, and hundreds of hours spent, I came to the same conclusion of those that came before me. That being, the F/S is simply too fragile with its short 'stick tang', and fine tip, to be used for any serious knife use...further, the handle design prohibit's proper indexing and retention.
Now, those are my stated positions, as well as the stated positions of the majority of persons infinitely more knowledgeable than myself that came before me...or you. But, as the old adage goes, 'Your Mileage May Vary' (YMMV)
That said, you'd be better served fullplate, IMNSHO, chosing a similar styled knife such as the Gerber MK II, Applegate/Fairbairn, or Randall Model 2. The F/S design is a classic, a part of knife history, and as such I still own a few...but as a fighting knife, its been proven in real world use to be a very 'poor design'...again, YMMV
As to Satin's question, in as few words as possible, let it suffice to say that the two handle sides of the injection molded handles, as supplied to BJK, didn't quite 'fit right'...which in turn would've required hand fitting to ensure a 'proper' fit...unfortunately, BJK wasn't in a position to hand fit many of their knives.
If you've ever followed any of the BJK vs RMK threads, you'll soon see that the final 10% of hand finishing of any knife can take upwards of 90% of the time involved. This 'time to cost' ratio would have quickly sunk a low overhead company such as BJK.
Also, if you still have a BJK A/F that has an uncracked thong-hole handle set, this probable cracking can be avoided by careful shaving of the contact surfaces between the handle halves.
These past handle problems are apparently not present on the current Boker A/F versions, due to use of their own handle molds, and are most definitely not a problem on any of the handmade/hand finished A/F's as made by custom knifemaker Bill Harsey.
Interestly enough, if Col. Applegate's confidant, Bill Cassidy, had stuck to Barry Wood's original recomendations for design improvement, this cracking/fitting problem would've never happened in the first place.
More on this later...
