Kitchen Knife Repair

Post by XT500 »

It’s a bit of a slow period in the workshop so time to dip in to the project box. (Some might remember the previous knife scale repair on the other site.)

This is an M&S serrated kitchen knife which was particularly useful for shredding lettuce and cabbage etc.

It has broken its back and had a fairly ineffective temporary repair and I wasn’t sure if it would be repairable or end up in the bin. I do have some loveless bolts in stock and a piece of purpleheart wood that Mr demographic kindly sent down.

With the handle removed, it’s fairly obvious why it has failed – the tang really needs extending. I have some 316 stainless mig wire in stock but unfortunately no stainless sheet.

You could cut up an old stainless eating knife to use for a tang

I would drill a hole in knife tang and counter sink a nut n bolt through handle. Fill countersink with resin for the likes for the sake of hygiene.

Sorry for the delay here, my posts have to be approved by a moderator.

Anyway,this is hard and blunted a couple of bits trying to drill a hole so resorted to the blacksmiths' technique of heating to red hot and using a tapered punch.

Delving into the scrap box, came up with an old steel rule of the right thickness.

After a bit of googling, I took a gamble and used the ordinary mild steel mig wire and gas for the puddle welds. The penetration wasn't great so ground off the welds flat and welded from the other side as well.

I've looked all over and can't find anything the right size.

Today's installment.

I didn't think this deserved the purpleheart so used a piece of oak instead. The handle thickness was originally 16mm so ran the oak through the thicknesser to 8mm, that allows .5mm on each side for sanding.

Thanks Weeksy, I know what you mean, it's a good job I don't charge by the hour.

I've always enjoyed making and repairing things so this comes under recreation for me.

Over the weekend, I applied some stain and a couple of coats of Danish oil.

Mrs XT's verdict - 'It looks a bit artificial but should look better after a few washes'. There's gratitude for you.

Aren't corby bolts a tad OTT for a pretty basic kitchen knife?
Good work though, it looks good

Thanks.

I had some loveless bolts left over from the first knife scale project which I detailed on the previous shed. This is what that one looks like today.

It'll be interesting to try corby bolts. Shopping time...

I have to confess I've never heard of either loveless bolts or corby rivets. Thanks for expanding my knowledge!
