New Handles

Hello there.

I have recently finished new handles for Masamoto KS 270mm gyuto and Konosuke Fujiyama White#2 270mm gyuto.

I must say that these are my favourite handles. Materials are Olive wood, Iron wood and white fibre spacers.

Tang in these knives are huge!!!

Original handle was to far from heel of the Masamoto. I moves it to the front. On picture below you can see two lines on the tang. Right one indicates old handle position. Left one is new handle position.


Konosuke got a new basic saya with Iron wood pin.

Hello knife people:D

Some time ago somebody called me and asked for sharpening his Global knives. These knives haven't been sharpened since they were bought so it is about 5 or 6 years now. I must say that one thing really surprised me.
I own three Global knives and I must say that these are really stainless. However 2 knives were in really bad condition. They had rusty dots. I thought that it will be easy to remove but after close examination I found out that rust started eating steel and  damaged edge. I don't now what was happening with these knives but deep rust on Global knives is strange.

Pictures of knives when I got them.

Rust I was talking about.

Edges in very bad condition.

Flexible filleting knife was bent. It doesn't look bad on picture bad it was worse. I used wooden stick and hammer to straighten it. It is better but I don't want to risk breaking the knife. I don't like this kind of knives. Their flexibility is making sharpening really hard.

Global G-2 chef and G-3  had strange scratches over the edge. Scratches are not surprise for me but their depth was very strange. I was refinishing blades on belt grinder and I didn't remove all deep scratches. It wasn't worth wasting the metal.

On  the next few pictures you can see deep holes of rust. Even after belt grinding they still exist. I will not remove all of them because I don't want to remove more metal than I have to. 

Here you can see edge damaged by rust.

Ok so I started from sharpening them on 300 grit stones to repair edges and to see what I have to do. After sharpening I decided to thin them down. This was the longest step of repairing but  it was necessary after repairs. After thinning I sharpen it again to check consistency. Then I took it to the belt grinder to refinish blades. I have sharpened them afterwards and I am happy with it. I will sharpen them again before they will go back to their owner.  It is not perfect but now these Global cut good and look good.

8 Wusthoffs project.

Hello there:)
Some time ago I was asked to make handles for Wusthoff knives. These are western handled and I do not have much experience with them. This is a reason why I decided to rehandle my old Wusthoff. You can see it few posts below.
Ok so now, after few months from my first contact with owner of these knives and finishing them, I am ready. 
New handles are made from Olive wood which is sanded to 800 grit sand paper. I applied camelia oil on 400 grit sand paper followed by 600 and 800. Then I used bee wax and hand buffed them. 
Also I cleaned blades with 400 grit ceramic belt followed by Trizact belt. Of course I hand sharpened all of them. I started with Beston 500 but I found it slow and slicky on these knives. This is a reason why I sharpened them on super JNS 800 followed by natural Red Aoto.

Wusthoffs when I got them. They were in very bad condition.

Old handles leftovers.

Olive wood for new handles.

Tangs have been cleaned prior to glueing.
