I bought one of these for my classroom last fall and it sharpened great. But is now not sharpening well at all. Is it only good for one school year?

It's conceivable that an attempt was made to sharpen something other than a pencil. In addition to cleaning it, you might want to either replace the blade or send it out to be sharpened.

I had very similar one and used like 20 years. I assume something stuck in/round blade which happens sometimes. I assume center core of pencil remains inside the blade. I recommend to clean. As long as your students use appropriately, it should last years.

I have only used this sharpener a few times for this and it does a good job. How it would react to multiple use is something I cannot answer.

Good question we have had ours for many years and have not had to sharpen. We purchased a new one for when we wear out this one.

I am sure it would dull over time. Not sure how it would sharpen. Ours is still going strong.

When i got mine it was really sharp. but after a few months of use i sharpened it with a sharpener i had around the house. you may need a better sharpener.

I'll answer your second question first. Yes. I use it maybe every 2nd or 3rd time I use the knife. Just a few light strokes is all it takes and there is hardly any steel removed. As for your first question its not so easy. I looked into some Global Knives and it looks like they are sharpened to a 12.5 degree bevel. This sharpener is set to a 15 degree angle. Your first time using it, you will have to use lots and lots of strokes on the 1 slot to essentially grind away your 12.5 degree edge and create a 15 degree one. Its what I did going from a 22.5 degree angle on my knives to the 15 created by this. It won't "hurt" your knife so much as change it. Although I suspect you would be hard pressed to notice a 2.5 degree change in the cutting angle.

How long did it last? I've went though so many electric sharpeners and this seemed to get good reviews, now I'm second guessing this one as well.

This is a great pencil sharpener for the price. I even let the kids use it (which normally I don't because they break things!!) Sound wise it isn't a tiny "hum", but it isn't SUPER loud either. Typical pencil sharpener noise, I'd say. Sorry if that doesn't answer your question. A pencil sharpener in a school is an important thing. They usually break or sharpen unevenly. Had this for 6 months and it's going great!

I've only sharpened it once, but it is not used daily. My other Victorinox knives seem to hold their edge fairly well and are used very regularly. I sharpen about once a month.

I have not used this sharpener for hunting knives but it does a pretty good job on kitchen knives. It's very good for 'refreshing' a knife that isn't as sharp as it used to be but eventually you need to have the knife sharpened professionally. If you use the knife daily, you would probably need it sharpened professionally about once a year.

Mine did not come sharpened. (That suits me better because I don't care for the points pre-sharpened pencils come with.) It is a wonderful pencil. They sharpen on center, the lead is dark enough for students who don't press hard. It erases well. The point lasts much longer than most of the pencils elementary grades students bring to class. I haven't noticed "hard spots" in the leads that leave scratches. The paint doesn't peel off. The diameter is nice for young and old hands. All that said, I would only use it for artwork (sketching) if I was in a tight, but it is a nice writing instrument. Mine did not come sharpened.

AS far as I know you can not sharpen it. I had mine for longer than 5 yrs. I also used it almost every day! You should only be using it to slice vegetables. I broke the hand the blade was fine.

I don't let the students use it and I don't use colored pencils in it or paper covered pencils, just to save the life. I also gently brace the top while I am sharpening. I think that all of these help the life, besides that it is a very good sharpener. It does have a setting for the fat ones kinders use (like the fat Dixon-Ticonderogas). I have had mine for a year now and it is still going strong. But, it sharpens them so sharply that you have to make sure the kids don't hurt themselves, (esp. kinders) I have third graders, so they are fine. The best pencils are found at pencils.com

I'll spend a good half hour stone sharpening it, and use a sharpening steel daily on it. After a stone sharpening, it goes dull in less than a week. Not sure if its factors I control (storage, improper use of stone, etc.) Or if the knife just goes dull that fast anyways. Yes, I use it in a professional kitchen. Its why I bought this knife, so I could have a decent one at work.

Yes. I do it all the time. I am a classroom teacher and I laminate everything. This is a workhorse and has lasted for many years. It does dull the blade so you need to change the blade every couple of months.

The point is very sharp and it is a good length. I sharpen my students pencils once a day. The point lasts the whole day, unless it is broken off. I really like this pencil sharpener.
