A) Nothing to complain about
B) Except the FUBAR factory edge .. It was , ............ FUBAR .

What we have is a 8.5 inch BB Flipper with a liner lock . The lock holds well .
Knife is smooth and fidget friendly .
It is by no means a small folder or a pocket knife . More a belt sized folder .
It's almost a transitional knife between a pocket knife and a fixed blade ( Size wise ) .
It be a very solid build , maybe not over built like some other TwoSun , but no light weight either .
It is a very nice slicing knife that is comfortable in the hand .
Oh yeah , 200 slice fail with a rolled edge ! ( Factory Edge )

Has been reground and maybe 30% of the blade toward the handle is still FUBAR due to the less than stellar factory grind .
I have to say , there is something to be said for a machined blade .. ( Accuracy ) .
The center line of the edge was out and is still out .. How many years of use to regrind / correct = Not worth worrying about !
Will go back to the rope with the fresh grind and see what happens .

Back to the rope with the re ground edge ..
Aaaargh ! A 300 slice fail with a rolled edge .. ( only a 50% gain )
Yeah , the edge rolled again ... A wood strop and the edge was slicing paper again rather well ...
But a fail is a fail ...
Leather stropped the edge back .... ( Hmmmm ) Should I run the stropped edge thru the rope ?
When the new guided knife sharpener gets here , I might have to do this knife @ 22 degrees .

I can only think the wet stone grinder , well it does a hollow ground bevel ! And might leave the 14c28n blade a little thin at the edge .
So a proper V bevel might not roll ( one can hope ) .
Come on snail mail , less snail and more mail .

Ok . so I ran the knife over the rope with the Stropped Back edge ...
Cant be bothered with the video ....
A 150 slice fail due to the edge rolling again !
Is it me , or does anyone else have 14c28n ? And does it tend to roll with heavy use ? ( Edge roll )
I am waiting for a new guided knife sharpener ... I have a few knives I want to run thru it ..
Also I have diamond sharpeners to 3000 grit ordered .

I put a 22deg micro bevel on the TS277 ..
Will this stop the edge roll ?

I think you can just make out the hollow ground main bevel ( wet stone grinder )

That would be a very slight concave edge.

300 slices sounds really good to me. In reality that would be over a year of ordinary use (for me) probably. I don't often cut something so hard, other than zip ties. I wouldn't be surprised if most of what you find re performance has more to do with heat treat - however, that doesn't change the results. Cedric got 215 out of a ruike (budget knife); but that was with 12° and a micro bevel (see from 5:30). Your original bevel is looking good and easier to maintain; was that at 20°?

Ruiks , I had 3 .. I gave one away ..
And I still have the two smaller ones ( Fantastic fidget knives )
I have another 14c28n to review and then that is enough I think ..
14c28n is just way disappointing .. ( The ones I have )
Id rather just stick to D2 .. Micro bevel was 22deg ontop a main bevel of around 18 degrees .. Just editing video now .

22deg micro bevel ontop the 18deg main bevel

Edge rolled again .. Thats 4 times in a row the edge has rolled ..
That steel may be way soft (?) I havent had at it with the diamond cutters yes ? So not sure how hard the steel is .
But a 150 slice fail due to a roll is not good ! So ...
200 slice fail with factory edge
300 slice fail with the wet stone grinder edge
150 slice fail with a stropped edge
150 slice fail with a 22deg micro bevel
And all fails as a result of a rolled edge ..
I think I am over Sanvik Steel ... Might put it away with AUS8 as a steel best avoided .

Just wish knife makers would stick to one steel ! D2
Because good D2 , I mean really good D2 can run with the big dogs ( Value for money ) .
So why do knife makers use steels they can't cook properly ?

I have to say , another disappointing knife from TwoSun ... ( Performance is disappointing )

So what steel is good for cutting through bone without chipping ?
I bang down on the blade with the heel of hand against bone to cut it and have chipped a few ‘good ‘knives .
Is d2 good for cutting bone and not chipping ?

D2 is good if correctly heat treated ..
D2 is tool steel after all ... Steel that cuts other steel !
I am a D2 Fan Boy as long as the D2 is correctly cooked .

Thanks . I have a couple svord knives which are not beat up which are Swedish high carbon steel and reading about 1095 and thinking about it that would be an old hickory also from memory not beat up resisting chipping and I would say the glock fm78 is good steel too .
So I am sorted if I chose the tool wisely now and that explains a bit about that .
It is a good test for knives cutting up frozen dog bones .

Don’t mind needing to sharpen a knife every now and then if I don’t have to baby it .
