Brisance
Brisance /brɪˈzɑːns/ is the shattering capability of a high explosive, determined mainly by its detonation pressure. The term can be traced from the French verb "briser" (to break or shatter) ultimately derived from the Celtic word "brissim" (to break). Brisance is of practical importance for determining the effectiveness of an explosion in fragmenting shells, bomb casings, grenades, structures, and the like. The sand crush test and Trauzl lead block test are commonly used to determine the relative brisance in comparison to TNT (which is considered a standard reference for many purposes).
Fragmentation occurs by the action of the transmitted shock wave, the strength of which depends on the detonation pressure of the explosive. Generally, the higher this pressure, the finer the fragments generated. High detonation pressure correlates with high detonation velocity, the speed at which the detonation wave propagates through the explosive, but not necessarily with the explosive's total energy (or work capacity), some of which may be released after passage of the detonation wave. A more brisant explosive, therefore, projects smaller fragments but not necessarily at a higher velocity than a less brisant one.

Sharpen Up The Knives
by: PuressenceEvery day I sit at home and sharpen up the knives
but it's alright, it's alright.
Today is the tomorrow that I dreamed about last night,
so shine a light, shine a light, but I...
Just wanna feel what I felt before, but I
I want you to know that I need it more.
Well the blind lead the blind
are the saints still alive since the last time?
At the end of the line
was I cruel to be kind in a past life?
Sharpen up your knives.
Every day I chip at stone while you are on your way,
up to the stars, up to the stars.
I don't know where I'm going to,
I don't know where you are,
but it's a start, but it's a start, and I'm...
Just gonna say what I, said before but I,
I want you to know that I need it more.
Well the blind lead the blind
are the saints still alive since the last time?
And I don't wanna stay,
don't wanna go away in a past life.
It's not alright
I've given up on horses hooves,
And I'm feelin more,
than just blue ribband blues.
And his advice,
before I dropped
Was be sincere,
whether you mean it or not,
