The correct production date is on the blade itself mext to the pivot. it would be interesting to know what dates are on the affected blades or on the JJ and GK knives. Did anyone take it appart and had a look?Blerv wrote:I'm assuming:
JJ = October 2010
GK = July 2011
Can we get an official confirmation there was a heat treat change between these dates?
Paul said once that it could very well be packing date so while I would assume 9 months or so would be different dates of heat treating a couple letters could be the exact same batch. Even the contrary could happen.
I'm not arguing against the logic above, just trying to derail a game of alphabet soup if it's meaningless. For the longest time I thought the EARLY codes were actually of a higher heat.
Seems I recall you stating that you traded them both back to the shop that you bought them from, for two new ones.CrimsonTideShooter wrote:I ended up selling the two GBs that I made the thread about.
Thanks! Mine is a "KK" fwiw.Alchemy1 wrote:I have 2 GK's as well. Look on the end of the box w/ the sticker. It will be on there.
Mine is also GK (on the box), but mine is an under-achieverCrimsonTideShooter wrote:The two new ones are GK. Bought from my local dealer right after he got them in a a couple months ago.
This means your knife was made manufactured in October 2001. The 2 letters are a code for date of manufactureBluntrauma wrote:Mine has a date code of JA but I have no idea what that means. My knife is perfect though.
What are your date codes now?CrimsonTideShooter wrote:The Mastiff, no one is saying the heat treat changed for sure. I said it was a possibility, and followed it up by saying that it was just conjecture since I never sent the knives in.
I have two VERY well performing GB's now, so I don't really have any say in this anymore.
Hell I must have dyslexia. When I looked at your message I realized the knife wasn't made in 01 and went back and checked. It's AJ. *slaps self in forehead*INFRNL wrote:This means your knife was made manufactured in October 2001. The 2 letters are a code for date of manufacture
What are your date codes now?
Mine is GK but I have not used it yet, so I cannot determine if there are any issues. Truthfully; I do not even know enough to probably even tell
Nice! I should be good to go as wellCrimsonTideShooter wrote:Mine are GK as well.

So your knife was manufactured in January of 2010. The Deacon has a link explaining the date code in good detail, check it out Date Code Explained
