The Chaves Redencion 229 Kickstop is the flipper version of the Chaves Redencion 229. Sprt of. It incorporates a Lee Williams Kickstop into the design, giving it what amounts to a disappearing flipper tab. The arrangement is very convenient and combined with the usual Reate quality, M390 blade steel, and durable full Ti construction, it’s a great knife and doubtless a winner for Chaves fans like yours truly. The real question is if you think it’s worth it: the Lee Williams Kickstop boosts the price to $410. I think that’s fine for Chaves fans, but the average knife buyer might gravitate towards the regular thumb stud Redencion 229.
