Not in that picture I don't.
Once the linen micarta is wet,the texture becomes like fine sandpaper.
Very grippy,even if coated in fish slime,mud,blood,etc.
Even though,I sometimes have a "quick lanyard"(zip tie and light rope) attached around the choil/top finger dip area if need be.
Also,I usually have my 16 with me in the 'yak,not the 1-7,as both knives fit my "poor mans flipper" sheath.
I will be making up some lanyards over the weekend,stay tuned.
