"What can I say?, works on nakamura/484 really well, had forward and back play with stock springs, got this set in and now absolutely no play, unfortunately doesn't work on the valet, they do say right in description they don't know all the models this size will work on, seeing as the valet is perhaps the smallest benchmade has made not surprising, hopefully I can find a set for the valet soon, overall this set is indeed beefed up compared to stock springs, not a huge amount but holding them side by side it's easy to see, to sum it up if you need new springs get this set, plus seller is fast on shipping orders out. Pic shows the size difference for the valet original vs the new springs."
