Slight change to blade flexibility measurement process

In February 2012 changes were made to the blade flexibility test to improve it's ease of use.  The weight applied & the distance measured were doubled to make the acceptable range easier to see, and basic science said that doubling should not change what passes or fails.  Additional precision was added, specifying that the weight would be placed 1" from the tip, with the intention of reducing arguments about where to put the weight.

On the sword blades tested, this made no significant difference, however, Lochac has demonstrated that on some dagger blades putting the weight 1" from the tip fails daggers that pass when the weight is placed closer to the end of the tip.

Thus, a slight but significant change has been made to the wording of the blade flexibility rule in the Corporate rules
To determine if a weapon meets the standard of being "reasonably flexible": Hold weapon parallel to the ground, supporting the handle against table or bench if necessary. Hang a 6-ounce weight (170 grams) one inch (25 mm) or less distance from the tip. If the blade of a dagger (out to 18 inches blade length) flexes at least 1/2 inch (12.5 mm) the blade is reasonably flexible. For a heavy rapier blade (18" or longer), the blade must flex at least 1 inch (25 mm). For use in cut and thrust rapier, the blade must flex at least 1/2 inch (12.5 mm). Any blade 18 inches or longer, being used in melee combat, must flex at least 1 inch (25 mm).

For kingdoms simply referencing the Corporate rules, this change is now in effect.  Kingdoms with the rules copied out may make adjustments at their discretion.


  1. I am unfamiliar with this color coding. Is the blue-background text supposed to be removed (like strike-through)?

  2. The orange is the colour background from the site, the blue is to highlight the change.

  4. Mistress Eyrny, a question, because I appear to have confused myself. (It's easy, I tell ya, especially pre-pennsic).

    But I will swear that when the measurement rules were first put in place, it stated that any rapier-or-CT blade, had to measure 1/2" deflection, and to use in melee, it had to measure 1" deflection.

    Meaning that blades that used to be C&T only, could now be used in single combat (but NOT in melee). But I can't find that writing of the rules anymore. All that I can find, including this new update ...

    Specifically state that all "Heavy Rapier" must deflect 1". (Which, in practice, means that the later "But in melee must be 1" rule, is redundant, since there is no C&T melee)

    So was this a change and I missed it at some point? Or have I misread the rules in the past?

  5. Yes, if a blade *used* to be C&T only but is flexible enough, it can be used in Heavy Rapier and melee. Yes, that part is somewhat redundant, but done on purpose, in anticipation of the eventual submission of a C&T melee experiment. That hasn't happened yet.

  6. It seems that a blade that is 18" long can be accepted under either standard? Or is it 1/2" for tourney and 1" for melee for the dagger as well?
