From my understanding they used 2 different kinds of springs in the frn ukpk, the first was a weaker spring and spyderco changed it through feedback and the next was a fork spring or something that was much tougher and felt stronger.gbelleh wrote:Is that the FRN model? If so, those do seem to have less stiff locks than any other Spyderco slip joints (at least the ones I have). They work fine, but I strongly prefer the very strong and stiff springs on the G-10 UKPK and Urban.
In the middle of the right side of the label (which is yellow, don't know if that matters), it says HK. The bottom right corner has TA02. It does have a split on the spring when closed. I'm assuming that means it's a fork spring? Either way, I feel it is safe and won't close on my fingers. Thanks for all the quick responses, I love how on top of things everyone is here.Donut wrote:What is the two letter date code on the box?
When closed, looking at the face of the spring, do you see a line/split in it?
Maybe it's due to the differences in notch depth/size between the half stop and full open position.GreatSyxsuke wrote:I played with it a little and now the spring is stiffer when it's fully opened. However, the half stop is still barely there in comparison. I don't fear it cutting me during closing but it's curious that it's stiffer fully open than half stopped.
That's true. Either way, the knife rules and I will be EDCing it as much as humanly possible. So glad I bought it, Sal is the man!Jax wrote:Maybe it's due to the differences in notch depth/size between the half stop and full open position.
The first person to get a UKPK with a split spring had a date code of March 2012. August 2011 is a little early.Jax wrote:Seems like your Ukpk was made in August/2011.
I also just bought a new old stock Ukpk and it doesn't have a split spring.
It was made in may/2011. 3 months before yours.
Buck knives I like seems dead on in his luck of the draw comment.
My half stop is strong,and my spring is stiff (but not as strong as other slip joints I suppose)
I agree that this is the most comfy spydie I felt.
And Soooo lightweight,a caly 3 on a crash diet.
