Kitchen knife blade damage - Keep using it or throw away?

[Legendary_Jarl]

My wife has this kitchen knife that developed a crack after a few months of use. I guess it's a heat treatment issue or maybe that the blade is too thin. Not sure how this happened but she really likes the knife.

Should I throw it away or keep using it carefully? Is there a way to fix it?

 

[gazz98]

Is there a corresponding crack on the other side?

Is it a decent brand? Shun has a 5 year limited warranty I know. Other brands might have something similar. For only a few months use, that shouldn't happen.

If nothing can be warrantied, I'd be inclined to ditch it. If you use it and it breaks, something metal and sharp might go flying.

Fixable? No clue. Out of my league.

Just run a bead of weld over and regrind it. Don't get it too hot or you'll need to redo the heat treat too.

I seen it on TV a bunch of times.

This is dumb and totally unnecessary advice. All you need to do is use some high temp superglue. Put a small dollop on, spread it with your fingers and hold the pieces tightly together with your hand for about 5 minutes. You should be fine after that.

What type of knife is pretty important.

If it's an expensive and/or reputable maker, contact said make (or retailer) and get it replaced.
If it's a cheapo, buy her a new one.

Drill a hole where the crack stops. It will prevent the crack from getting worse. It should be good to go after that with moderate use. It would be advisable not to drop the knife.

Is the crack far enough out that you could cut it there and regrind it into a short kitchen utility knife?

 

[pholder]

Snap it off at the crack, reprofile it and keep on keeping on

 

[jbmonkey]

toss it, if no warranty. it's going to completely fail and someone might get hurt. no kitchen knife, no matter how much loved or liked, is worth that risk.......

I would throw it out. Try to find out what caused the crack. A properly treated blade should not crack, especially after o lying a few months.

Depending on where the crack is, you could grind it into a smaller knife.

If that were not an option, I'd throw it away.

I would reply but now all my hands are glued together.

Another vote for tossing it.

 

[Ernie1980]

I would, like stated above, snap it at the crack and make it into a smaller knife. That depends of course on where that crack is on the blade, can you share a picture of the whole knife?

 

[toker]

Turn it into a Nakiri or Seax?

 

[bigsurbob]

Toss that thing dang.

 

[Alberta Ed]

Toss it and buy her another better knife.

Then my plan was successful

I would toss it and buy her a better one.

For food prep the risk to me would be that the crack could hold bacteria.

Or possibly get metal bits in whatever I'm cutting. Toss it!
