### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    The overmolded handle has a touch of softness and good grip which makes it very comfortable in the hand
  

*by A***R on Reviewed in the United States on March 21, 2017*

Really liking this 6in joint knife.  The overmolded handle has a touch of softness and good grip which makes it very comfortable in the hand.  This knife is a little heavier than my last 6in knife (6.9oz compared to 4.25), but it feels very solid and well balanced.  I would say the blade has a medium to stiff flex.  The nail setter is hefty and will have no problem setting proud nails.  Price is a little high, but I feel like it'll last, and I don't mind paying a little extra for well made tools.

Best 6-inch knife I've ever used, very well balanced and not too heavy or light. Great grip and clean design.
