Hi there, New on here so hope I got the correct forum. I am reconditioning an old planer ELU DAH 176. Date stamp is 1983. I am having no luck finding replacement knives. Any I have come accross for this machine are different than the ones fitted. The knives are 210mm long x 16mm wide and 3mm thick. They are reversible and have a continuous groove running down the back. The groove is 2mm wide and 1mm deep and is rounded at base. I found one photo online from a german/swedish forum which say Elu no longer have these knives. Any help would be most apprerciated or any other knives that may fit.
