Accessories&twin knives

Mar 11, 1999
What do you think about accessories of knives?
I always wish large knifves had scissors,stell pointed stick,small thin knife,and stone.
Gerber BMF,Buck M9,Randall,and some survival knives have small stone.I think it very good idea,but not enough.
Scissors is great help for cooking,fishing,paper and cloth dealing,first aid,etc.
Steel pointed stick is very convenient to dig,slow for self defence,fire work,etc.
Small thin knife is needed for hunting and all close works.I think drop point blade&seepfoot selated brade combination folder is best.
Is there some other good tool to large knife?
As I think why only a little fixed knives is twin?It is very useal.
