just shoot me now

FYI the fabric wasn't even pinned, it must have been a stray pick up, I did have a bit of a mess going on with a patchworky experiment. There was a pin (I found it), the upper knife did break, so my fault entirely. No other damage TG, with knife disengaged it all still operates perfectly. What a little trouper, I shall give it a nice clean out while it's on holiday.

Shake that fabric out!

If anyone knows of reasonable European suppliers I'm interested. Have asked for a price from my sm & serger supplier, but their feet are usually pricy.... we'll see, being weekend I can wait till Monday to order.

Thanks!!! I was so so sad!

I decided to get a replacement for the upper knife and a set of knives, just to be prepared...
Shopping around has saved me 52.26. yes, saved me that much. My first price enquiry for 1 upper + a set of 1 upper and 1 lower returned was 90.59 incl P&P. *shudder* ... I started more enquiries and got the same quantity (1 upper + 1 set of both knives) at 38.31 incl P&P, ordered that quick *whew*

I am really missing my serger though, so at least I now know it was totally worth getting :)

Fingers crossed I get it before the weekend, and can manage to install it!

I thought most overlockers gave you an extra upper knife blade in the box just most times, but I guess not on that one.

The deal is though, the upper knife blade is made softer than the lower hardened steel one on purpose. So most times it would give or break before the lower one would, when sewing into a pin, and then if you do something like that, most times you only have to replace the upper one. Ditto when your knives just get dull from sewing with them, most times you would have to replace the top one just many times before ever having to replace the bottom one, just since most times they are made even out of different hardness of the metal.

So that was probably why it was so expensive, as the expensive part is probably that lower blade that would not get replaced for a lot of people maybe ever or for just years and years.

It is really expensive no matter what or how little it costs to replace a lot of upper knife blades by just sewing into a pin, so I think that is the incentive to make sure not to do that, I know it is for me.

But don't throw away your existing lower knife blade, as good chance it probably or might be still just fine too. If it's fine, don't even swtich that one at all. Just keep the new lower one on that instead, so you always have it case for when you really need it someday.

I read somewhere, some time ago that one shop requires their staff to learn to serge without the benefit of the knife...sounds easy.......no. The knives are engaged while serging.

It can be done as long as it is not necessary to trim, which you would need to do pre-serging.

Knock on wood, I have never broken a serger knife!

You can sew without the knives engaged. It is necessary for decorative stitching on fabric when not on edge. Can do tucks and stitches in middle.

@beauturbo
I hadn't noticed a spare when I opened it, but didn't look after the break! So I checked but no, didn't get one. Ah well, it really was a bargain price serger and I got loads of other stuff with it so that's ok

I thought I was careful, that's sortof why I posted. It was careless but not because the fabric was pinned. I was playing with fabric scraps and there had to have been a pin residing from *whenever* Real pest but a good lesson learned.

In the price breakdown one was more expensive than the other but I can't remember which atm. I will only replace the upper this time and keep the set, hopefully never need to use it :)

@PattiAnnJ & Twizard
I did that! I trimmed the seams to 1/4" and serged them. Got a pretty good result too but do miss that knife. I've not tried serging not on the edge. Not sure mine does that, is that for a 3/4 stitch machine? I read the manual but it seems to have gone straight through, the excitement probably :)
Knockin' right back at you PattiAnnJ, hopefully never happens.

@kowgiirl.up Whew! yeah, thanks!

Never meant to imply you couldn't, it is just eye/hand coordination to do so with the knives engaged.
