I think the SOD or 711 are the most functional if you need to take one knife.
If you got the option to take 2 , take 911 or 1311 with a 411/311 of scrapper 5.
Where are there picture of the new tali-whacker? I have the original one and think it's a great knife, but never tought that they wel remake that model for the general population...
Kind regards,
greets
