Note… these pictures are not mine, they are used as examples.
@ muto & whoever……
The two picture below are fairly representative of the ‘lockup’ my GoCommas have.
About 85% - 99% of the lockbar fully engages the angled heel of the blade on the 5 of mine I checked. IIRC Chris Reeve considers 80% fully acceptable. Good enough for him... good enough for me
.
This is referred to as ‘early lockup’ and is GREATLY preferred by me. ymmv
NOTE: Do not be concerned with the thickness of the blade & thickness of lockbar. Be concerned with what percentage of the lockbar engages the blade.
NOTE 2: Of course if you have a knife with a super thin lockbar… it should go without saying THAT IS NOT GOOD. .
.
The two pictures below are examples of ‘late lockup’. You will notice the lockbar touches or almost touches the opposite side liner. To me this is in no way desirable & a total deal breaker. This condition is where you will begin to get up & down blade play.
.
The modern linerock was pioneered & patented by Michael Walker in the 1980’s & 90’s.
If anyone is afraid their lock will fail…. they should Test It.
Spine Whack Test
- Hold the knife in a manner that ’if’ the lock fails you will not get cut. Give the spine of the blade several good whacks on your knee, a table top, a heavy piece of wood, something substantial.
See for yourself if it fails. No use wondering or speculating…
EDIT: . Just did ‘Spine Whack Test’ on the 5 I mentioned above. All 5 passed with flying colors… solid as a rock.
Not surprised at all…. …
