Just something to consider... I too found the mini Grip handle a little too small for my tastes. There are a few old and new options from BM which you might find close to the price of new scales (particularly if you find one used): mini bone collector, mini presidio (1 or 2), mini barrage, etc. Many online dealers will give you a closed measurement of these knives to compare to your mini grip.
I don't remember the stats for the mini freek or mini Boost, but they might also be a little bigger.
