I'm curious how L.H.S.'s experiment worked out. One of the reasons I started following BladeFroums was this particular thread that got me hooked.
I have carried the same 78 smooth white bone as L.H.S. every day in 2018 (save for 7 days - 6 when I was out of the country and 1 when I used an SAK while camping and just plain forgot the 78 in my tent).
Here's some pictures as 2018 progressed...
Day 1 - sometime around December 31, 2017
Sometime in June - on my in-laws farm
July-ish
August timeframe
End of December, 2018
This knife has been on many, many adventures with me and will never leave my possession. I learned a lot about this pattern and about the adventures with having one "main" knife throughout the year. Of all the knives I accumulated in 2018, this 78 surpassed them all for my 2019 carry knife........ all but one....
For my daily carry in 2019, the 78 in smooth bone will be un-throned by the grail knife - the 85 in polished stag.
