Hello Neil,

I have only just spotted this, a decent offer I think.

Thank you for drawing attention to it

Regards

Brian

I have often wondered why they don't make these squares out of stainless steel. I have a small stainless steel one that I like and use a lot. It is hardened and can be left out with no fear of rusting and does not need a coating of oil so is very pleasant to use. It is not as if stainless steel is that much more expensive for a that size of item.

I can remember our engineering teacher, when we were leaving school to go out into the world of engineering saying not to get stainless tools, rules, calipers (inside and out, and odd leg), and squares. I think the reason was that the stainless, although hardened, was not as hard as carbon steel, and he did say that they won't go rusty if you are using them. I got all those tools for Christmas 1963, and still have them, the 6" rule unfortunately lost 5/8", it snapped like a carrot.

Some say the same about knives, stainless not holding an edge as well as carbon steel.

I agree with you there about knives, in my experience the carbon steel knives are greatly superior at holding their edge

I don't have any trouble shaving with stainless steel razor blades

I do t think razor cartridges have stainless blades,but I will check.
I make knives and studied under a Sheffield little mester who taught me a little about steel.
A carbon knife and a stainless knife will take an equivalent edge, put them in a drawer and leave them. The carbon will dull overtime due to micro corrosion, the stainless will be as sharp as the day it was sharpened. Bear in mind a razor edge hand ground in Sheffield was unable to be examined by an electron microscope as the operator said it was too fine to focus on. It may not be as resilient as a carbon blade in use though. The old cutlets derided stainless as being unworkable and not fit for blades, it's main use was seen as being a suitable material for water pump spindles.
I prefer carbon steel tools to stainless as we look after them by and large so no need for such corrosion resistance.

I quite believe you on the corrosion on the edge of knife blades, I have a hunting knife bought about 40 years ago, it's marked no stain-chromodur - Inox. When I got it you could shave with it, now you can still shave with it. I have not used it, and it's never been sharpened.

There are dozens of stainless steel grades. Some rust quite easily and others don't. Some are hardenable and others aren't. Saying that stainless holds its edge is like saying dogs are brown.

I'm currently (still) in discussion with Franke about why my kitchen sink (304 stainless) is peppered with holes. But that's another story that has some distance to run....

It was set up for advertisers' announcements and was not intended to be a discussion topic.

I'm not trying to be negative about the product but does anyone else think that they should say where they are made and not where the office is?

Thanks very much for this notice Neil - one is winging its way to me now. Cheaper than buying one in NZ.

I doubt Machine DRO know where M&W make them.

Bowers group, M&W are advertising for staff at there Bradford factory, to work in a high precision engineering environment, so it appears they still manufacture there.

I don’t think so either. I think they’re normally carbon steel with a couple of rust resistant coatings?

Ian Hewson, your post should maybe put up in upper case letters, that's worth shouting about.

Neil, it was Machine DRO that told me most of their (M&W) kit was now made in China. It's like cheap chinesium Record vices saying "Record Sheffield" rather than "made in Sheffield" hoping the buyer will think it's English.

No doubt true. China can make equipment to any qi quality level you want if you are prepared to pay, and if M&W can get their kit made to specification cheaper in China, who's to blame them?

Agreed, and country of origin has absolutely no guarantee of quality, or the reverse, but my bone of contention is that there was a time when things had to say where they were made, so if you see Sheffield on something you are likely to assume the item was made there.
