Re: [Histonet] Cutting defect and blade adjustement
To tell you the truth, I have both. The worst are the vertical,
because as you say, they seem to be caused by a tiny nick, but I have
also tried with a brand new knif and it happen (less but it happen). I
am a newby but the last year I cutted a lot of blocks and I was hoping
to overcome those problems but even with brand new knifes it happen...
About the horizontal stripes, (the venetian blind artifact or
something like that) I guess it is caused by blocks that are too soft,
but I will appreciate any help about it. I think maybe it is better to
let the blocks dry or cure for a long time before cutting them. Here
in Cadiz (SW Spain coast) it is very moist and warm and I think it may
have lot of influence.
Thank you for your help, I wait for more if you could .....
