Rockstead Knowledge Thread

My only guess is that if you used old jeans, maybe they accumulated some particulates in them that would be abrasive? Shot in the dark over here.

Yes, either that, or liquid Flitz is a different formula than the paste. I'm thinking the liquid may have a more coarse grit of Silicon Carbide in it, or those are some seriously tough jeans:D

Look on the bright side, now you don't have to worry about acquiring your first scratch. Put in pocket, use like heck, smile, repeat:thumbup:

I considered the same thing. I used the flitz to polish a watch band and noticed some scratching too. I'll also try the paste. Any idea what the grit is? I'm going to just get some pcd from ken shwartz(sp?) and yes! I'm going to use the heck out of it now :D

I read somewhere that Flitz is around 3μm, but personally I believe it's a bit finer than that. 3μm seems a bit rough considering the great results I've gotten with it.

Thank you. I'm pretty sure ken Schwartz has a pcd that is around that in grit. I'll also be able to throw some on my strop for the Weps. I really freaking hope this works. [emoji31]
 
Yeah the jeans were an older pair from storage. They were clean. I used the liquid flitz. I'd say about the weight of the blade. I was pretty hesitant to do it because it was my first time doing convex. They are definitely scratches. I used a chamois and microfiber cloth to clean the wet flitz off. They aren't deep scratches but very noticeable.

That sucks and sorry to hear it. Did you let Flitz dry before stropping?

I used it while it was still wet. Does that make a difference? I'm going to wash a pair of jeans and try again. I'll also let the flitz dry this time to see if it changes anything. Thanks!

I dont know if letting it dry will not make new scratches. Was asking because on the Rockstead site they let the polishing compound dry before stropping. Btw, I've been stropping my Chi on green compound/leather strop.

The Flitz liquid polish is watered down version of the paste - according to Flitz. Not sure you are going to get better results with paste.

Great info man thanks! I also remembered that I didn't shake the bottle before applying. It may not be a huge deal but I'm guessing it could have played a part since it wasn't used properly. I did use a leather strop with .5 micron paste. It was able to remove some of the scratches left by the jean and flitz strop.
 
Found this video by accident and how this guy uses a Hizen hard for 3 months straight and shares his thoughts. Thought its worthwhile to share.

The video is in Russian, but I took some notes to relay the gist of what he is saying.... All good about ZDP and this guy is a hard knife user and does not baby any of his blades both expensive or not.

The video is here https://www.youtube.com/watch?v=HnA7ihIrmbQ

The transcription, not 100% accurate, but best I can do:

He works in construction and is a knife nut. He uses different knifes in videos. He loves the Shirogorov and the Rockstead was the knife to make him put it away. If you watch any of his videos you can see he is a hard knife user.

3 months of hard use at work. His finish on scales is rubbing off where the knife is inserted into pockets.

He dropped on concrete and had to polish the side of scale.

The clip stayed in good finish.

ZDP blade. The angle of 30 by 24. He tried to sharpen the blade and because of geometry he was nat able to do sharpen it. When he started with diamond stones it started to scratch and chip. Then he used a cheap synthetic stone at 8k. He said that even at 8k still could not get a mirror edge.

Then he came to conclusion that using a paste is what works. So he stated to strop to maintain the edge. It was simple to bring and maintain the edge and keeps it working sharp.

He has a few micro chips on the blade, but they do not affect the cutting. He shows it in the video how it still cuts thin paper. Then he cuts a tomato and other fruit. He likes how it cuts and his blade is still quite sharp. He keeps talking while cutting about how much he enjoys cutting with Rockstead.

Then cuts a 1cm nylon rope (don’t know how to translate that). Then he does some wood cutting of oak…. he says it does not byte into the wood really hard, because of geometry. Checks sharpness against a thin sheet of paper… No problems… not a hint.

Then shows his stop with 2 different polishing compounds. One of which is similar to Flitz. Keeps saying how sharp and how long the sharpness lasts. He loves ZDP.

Knife is simple and he likes the looks and how it cuts. He understands/respects how Japanese know to work steel in traditional manner.

He talks about shinogi-zukuri and what it is. He says there is no magic, but they have a unique qualities. Talks about how expensive knives vs tools and how he thinks that some have a designated use which is not related to intended use. Like cutting nails, opening cans or other stupid knife tests. If used as intended there is a long life span for the blade and how sharp it will stay.
