Talk:Glass knife

message: superior in most ways to more brittle metal blades
What? No, glass is harder than metal, but much more brittle, hence glass shattering and metal bending. Common sense. This article is really suspect. --NovusQuestus 21:58, 14 February 2007 (UTC)

message: the manufacture is unclear to me: I understand the square of glass with a certain thickness is scored that broken diagonally. it des not specify which edge is considered the knifes edge. Is it the scored diagonal? the non-scored underside diagonal? these have knife angles of 90 degrees. Or is it the one of the 2 short edge between the new long thing diagonal face and long thin original thicknessside of the square of glass. these would have knife angles of 45 degrees. Is there a way to construct sharper knife geometries? references are welcome!  — Preceding unsigned comment added by 83.134.175.12 (talk) 23:07, 26 June 2012 (UTC)

message: Hi,
I have made a few changes in this article by using my sandbox.To cite this article, I used U of T library and Google search as database. I have added a several new references and have edited a couple old references.However, I find that there are many parts of the article needed to be cited. Moreover, insufficient reliable sources are used in this article.I have placed "citation needed" at the end of the sentences wherever I found it should be cited but I could not find any references which are related to them.  Therefore, it would be best if there were some experts can improve the references in this article.
The following is my sandbox link of this article:

message: Can we please avoid this colloquial and very, very, VERY unscientific wording? What is "x times less" even supposed to mean? What would "1 times less" equate to? What about "0 times less"? Andersenman (talk) 10:25, 30 October 2016 (UTC)

message: Zirconia is not a glass. To the best of my knowledge (limited) it's only found as a crystal. The only thing it has in common with glass knives is not being metallic, which I am not sure explains why it's in this article. IAmNitpicking (talk) 15:19, 8 January 2023 (UTC)
replies: text: The article doesn't claim Zirconia is a glass. It is referred to in passing as a current non-metallic alternative to glass knives for culinary use, which is fair use IMO. Plantsurfer 18:49, 8 January 2023 (UTC)
