Is this normal? I have a Case Equal End Pen probably from the 20's or 30's. I can actually bend/flex the blade 50 to 60 degrees.

This is a factory ground blade, but it is ground almost wafer thin, and flexs like a mini fillet knife.

I've never seen another pen knife do this.

Is this normal?
 
It's not normal IMO and i would stop doing it because it's liable to break.

i imagine its a good thing, unless it cant hold an edge...hows the edge:confused: if its sharpe thats one heck of a wonderblade:D
 
It's so thin it's sharp by default, as far as how's it hold an edge?
It's so old, and never been sharpened, so I really dont know.
 
that sounds like on heck of a knife, it seams to be wonderously made, just dont try jusing to pry with it lol, sounds like it has a great temper:D
 
I bought it at a local estate aution listed in the local paper, the guy must have had 100 knives in his estate and it was me and one other guy bidding. I bought 30 knives that day and spent less than $100.

Some were old advertisers, George Schrade Wire handled Girl Scout Knife with the Green Tin Insert, a Roebson Sure Edge Equal End Pen, Kent, Camcos, and a slew of others.

This was my finest knife day. :D
 
Nice Case. I am very partial to slip joint folders and Case ones are classic class. Could that blade have been a grinding mistake. Yow, that looks like the smallest fillet knife I've seen - fillet anchovies ? Unfortunately, I think the older vintage Cases are better made than the current lot. I bought a 3 blade one 2 months ago and I didn;t bother to open the main blade. Everything else looked cool but when I got home, I realised that the blade actually didn't even have an edge bevel on it ! Probably just an oversight at the factory - very unfortunate. I have to say though, Case is one of the few factory companies that actually does a decent mirror polish on their new blades.
 
DON'T do it. Even if it returns true you stress the crystal structure in the blade and, sooner or later, it will snap.
Why ruin a fine knife for no useful reason?
 
As steel gets thinner, the arc it can take increases, so it is not surprising that you can bend that blade as far as you can. I have bent fully hardened 1/8" machetes past 90 degrees for example. In regards to harming it, the lifetime of that level of stress is on the order of 100k-1000k bends. The only way to harm it would be to bend it to the point of which is stays bent, do that a few times and you can crack the blade.
