Need help with reshaping a blade.

captain spaulding · **on:** August 29, 2011, 09:55:33 AM

I bought a Opinel for $1 that has the tip of the blade missing. I am going to clean it up tomorrow but am thinking I should reshape the blade to give it a point again. I have a Dremel that I plan on using for this. Can anyone give me some tips or is it pretty straight forward? Thank you in advance.

Think about bringing the spine down to meet the existing point or you might end up with a sharp bit when the blade is closed, maybe

Make sure you don't get the steel too hot or it will loose its 'temper' and the steel will be soft
It might be better to use a stone

Good luck Captain

Possible sharp bit when closed

Thank you sparky415 I did not even think about that. I am going to think about it while I am cleaning it and then make a decision. I will most likely end up doing it the way you suggested. Thank you for the great visual with the photos it helps incredibly.

ZED it is a NO.10.

cheers mate, my next # to get

good luck , these are easy to mod, i drilled a hole for a lanyard on my #8 a week ago and might do some more work on the handle, there are plenty of mods you can do to these knives,

just watch it though as they do mate

ZED do you know how to get the blade lock off of them. When I was cleaning mine I got some sandy material in there and now it is almost impossible to twist the lock. I need to take it off and clean it. Any ideas.

captain spaulding · **Reply #7 on:** August 29, 2011, 11:17:16 PM

Here is what I did to it in the last hour. It was my first time reshaping a blade and I do not have a clamp so I had to hold it with one hand and grind with my Dremel in the other. It is much better than it was before so I am happy. I accidentally touched to the tip with the dremel so that's what that mark is on the tip. What do you think.

The No 10 is the best sized one ever made Captain

That is looking a lot better now!

To remove the ring (I have never done this myself so watch your fingers)
I copied this from a Utube comment
Lock the blade closed. Then grip the blade at the notch with a pair of flat nose pliers, point the front of the knife towards something soft, and pull open the blade. The blade will push the locking ring up and pop it off the knife (and if you didn't point the knife at something, it will fly across the room). It makes a sound much like the en bloc clip ejecting from an M1 Garand!

Thank you for the info on removing the lock. I will let you know how it goes. I love the sound of the clip ejecting form the M1.

As I said I have never done this so don't blame me if there is blood

Good luck

captain spaulding · **Reply #11 on:** August 30, 2011, 12:11:56 AM

Well just tried and that will not work. You cannot close the lock when the blade is in the handle as the blade blocks the lock form sliding past. Any other ideas?

You can see here how the blade blocks the lock.

I found this. You have to translate it though.

Sorry about that, I guess they must have been using the older style knives, the blades don't lock closed on the older knives
I don't know what to suggest now, maybe someone else will have a better solution for you

While you are waiting there's some more stuff about Opinals here

reply no 97 looks good to me

Just found this. I guess I will just pry it off.

Yes, it sounds like an older Opi without the additional notch in the Virobloc ring. I use a pair of C-clip pliers like that shown in the link...the jaws spread when the handles are closed. The opening the blade trick on a locked knife never worked well for me.

captain spaulding · **Reply #16 on:** August 30, 2011, 12:32:48 AM

I just pried it off like in the YouTube video and it worked perfect.

Sparky415 · **Reply #17 on:** August 30, 2011, 12:36:01 AM

Still got a full set of fingers?

Sure do. Putting it back on was the hardest part. It is still tight. Any ideas anyone. Should I take it off and bend it open a bit?

Spork, Lord of Lime Jello! · **Reply #19 on:** August 30, 2011, 12:45:09 AM

Still tight as in hard to turn? It may be the heads of the pivot pin may be a little high or rough. Have you tried greasing the inside of the locking ring?

Yes hard to turn. I put a bit of gun oil in the collor before I put it back on but it seemed to not help very much. Maybe I need a thicker oil. The funny thing is it would turn fine before I even started messing with it when it was all dirty.

Spork, Lord of Lime Jello! · **Reply #21 on:** August 30, 2011, 01:37:36 AM

Maybe the ring isn't fully seated? Do you have any light grease?

I am pretty sure it is fully seated. No I do not have any grease. It was turning fine when I bought it. I used a rust removing bar to get the blade nice and clean. After that it felt like sand was in the collar when I turned it and it became hard to turn. I finished cleaning and shaping the blade and sprayed the blade down with oil. I took off the collar and cleaned it and oiled the inside of it then put it back together.

Spork, Lord of Lime Jello! · **Reply #23 on:** August 30, 2011, 01:55:15 AM

Hmm...I dunno then, unless the ring got tweaked a bit. That's pretty hard to do though.

Yea not to sure what happened. Maybe someone else will be able to tell me later. Thank you for the help anyways.

Did you try polishing the surfaces that slide over one another with something fine, like 1200 grit sandpaper? Or maybe 1800? I used 600, 1200, and 1800 on the axles of my son's pinewood derby car, and they were practically mirror finished afterward. (We still only came in second though!

)

They already have a pretty good polish. I have been messing with it for the last hour or so and it has become easier to turn. It is easy enough to make it usable so I am good with that right now.

I'm glad everyone still has the right amount of fingers

I used to cut myself every time I picked mine up when I was a lad
