    Question

    While in Atlanta I noticed the absolutely perfect, knife-sharp, cut made by the Morso on display. I asked Michael Moriconi of Tech Mark about it. He asked if my blades are hollow-ground when sharpened, and told me that all Morso- (and Jyden, I think) blades are made hollow-ground. Now, I get a good cut, but this was really good. And for a teeny shop, I change my blades 4-5 times and year, and yet I hear a big shop should only have to change them twice a year.
    When in Portland I stopped by my sharping company and told them the story. It was all news to them, and they said the new Morso and Jyden blades they get in are not hollow-ground. They do a lot of framers blades and are willing to dedicate a machine to the purpose if enough framers want this service. Apparently, it will cost a bit more, but the edge will last many times longer.

    I called Michael and he is sticking with his hollow-ground story--they should always be ground that way, and they are manufactured that way. He was willing to talk to my guys about it. So I faxed all info to my guys and now I am trying to bolster my position with facts from any of you whose sharpening services do the hollow-ground method.

    What I'd really appreciate is knowing which companies do it, and how long you find your blades last when they do it, and the cost, if possible.

    Thanks, tons.

    I always like very sharp chopper blades and would change sets every two weeks. What ever it cost was made up in faster corner fitting and less time spent fixing corners on fitting.

    FYI two weeks = 50 - 100 frames, many larger 2 - 3.5+ inches widths

    I used Quality Saw & Knife I'll call and find out. They've been advertizing in Decor for thirty years.

    I have found that TechMark is not only
    the only place to have Morso knives
    sharpened properly, but also the only
    place to buy genuine Morso blades. I
    have bought new blades from both L-J and
    United that said "Morso" on the box, but
    were not hollow ground. If the blades do
    not have"Denmark" stamped onto the blade
    itself it is not a genuine morso blade.
    I have had new blades ruined by other
    shapening services, one which has been
    advertising in decor for years, by
    grinding surfaces on the blade that
    should not be touched.

    Well, duh! Why didn't Tech Mark tell me they sharpen?

    And that explains why my sharping company thinks they are getting new Morso blades in that are hollow-ground. If you have not objections, I'll copy and fax this to my sharpening company.

    Also, Pigeon, which company that adverts in DECOR does this wrong? Not Framer's recommendation, I hope. You can email me privately if you are reluctant to say so here.

    Again, thanks for all the information. This matters to me.

    Lets say old dogs can learn new tricks. I got a new chopper and the blades have been WOW. Now it time to sharpen them. I just sent a an old set to the place I've been dealing with and am not a happy camper. I want to send the new set out to the best place.

    What our my choices

    Tech Mark ?

    If so could someone post their address and phone number and cost to sharpen.

    Interesting,

    This discussion ran it's course on the PPFA On line Exchange a few months ago. The concept made sense, but when I went to check my own blades (22 years with a Morso), I found that they are NOT Hollow-ground, BUT they've been cutting just fine. ? ? ? ?

    Wanting the "Whole" story, I stopped by to talk with Tove Peterson, owner of Morso during the Birmingham Spring Fair, back in February. Here's what I learned.........

    The Hollow grind is done on such a large wheel that it is very subtle, and difficult to see. It does improve things, but only slightly over a straight grind (IF IT IS GROUND WELL).

    By the way, the sharpening service we use is based in Minneapolis, and probably grinds about 95% of the Morso's in a 5 state region.

    Always wanting to know more......

    John

    Question

    John ; I too have spoken to Tove ( OR tried to we don't speak the same language equally) so I didn't get to ask some important questions.Maybe you can interpt for me.If staight grind works why do they suggest Hollow grinding on their manuales? Could it be that the hollow grinding is more likely to produce a better edge? You know, sort of like the stropping on your Grandfarthers straight ( Hollow ground) razor really finished the job or jst gave it the right touch.
    Also don't you think that if a blade is done wrong ,hollow or straight ,it won't do the job?
    Framer I think in the search feature you can find a post by me with Tech-mark's address ,but their should be a lot of people that can do the sharpening right ,hollow or otherwise.Someone once told me to feel the edge of the knife on the face and back to see if thereis any feathering or rolled edge no matter how slight .This is what ruins the cut .I think this acts just like a dull blade.
    Hope this helps in some way .

    Hi Buddy,

    How nice to hear from you. How's the new job going?

    I guess I do not understand your last line comment in the message above. Could you please elaborate?
