I just received my Evo S557 today and here are a few physical measurements, and a few opinions between the S557 and my Vic Explorer and my Vic Deluxe Tinker:
Over all length: DT = 3.5" S557 = 3.25"
So, if you have large hands, the DT is going to be a little more comfortable to grip and use.
Judgement: The Delemont knives should be as long as the Vic knives.
Cutting blade length: DT = 2 5/8" S557 = 2.5"
The DT has a slightly longer cutting edge, but the S557's blade locks open (but I do find the lock to be a bit uncomfortable in the hand while using the knife).
Judgement: Longer cutting edges are better. Locks are good, but maybe a lock back design would be better.
The can opener/small screwdriver of the two knives appear to be the same, but they are not.
The DT can opener is 1 1/4" in length while the S557's is 1 1/8" in length.
Judgement: meh.
The bottle opener/med. screwdriver:
Bottle opener length of the DT = 1 1/4" S557 length = 1 1/16"
The bottle opener on the DT is longer and has a half stop, but the opener on the Evo locks when pressure is applied.
Judgement: a locking screwdriver is good.
Why doesn't Victorinox make all of the tools lock then pressure is applied?
Scissors:
DT cutting edge = 1" S557 cutting edge = 3/4"
The DT has a bigger bite and is very precise but I like spring system of the S557.
Something else I noticed...
Years ago I didn't like the Wenger serrated scissors because they left a jagged edge on the cut paper.
But Victorinox has changed something...
The S557 scissors appear to be serrated but the cut paper was smooth and not jagged!
The reamer/awl/sewing needle are identical as far as I can tell.
The pliers...
Over all length of the DT = 2 7/8" S557 OAL = 2 1/2"
Bite depth = 10/16" Bite depth = 9/16"
Bite width = 13/16" Bite width = 1 1/4"
Only time will tell which is better.
They both seem to work reasonable well.
The scales...
The DT has the typical Vic shield inlaid silver while the S557 has a white applied Vic shield.
The tooth pick and the tweezers are identical.
I really can't say which is the better knife.
I'll just have to use them for a while to see which one bonds with me.
So for the rest of December and all of January I'm going to shelve the Deluxe Tinker and just carry the Evo S557.
