Move Informartion

Should some (or much) of the detailed information in this entry be moved to more specific entries, such as "Hand Saw"? Thoughts?

I'm not sure what you mean by detailed information other than the stuff on saw terminology that applies to most saws. I think that it does belong here rather than repeating it in every article. The rest is just a brief description of each type of saw, with the appropriate link. I do think that this article needs to mention concrete saws, masonry and rock saws as well as some mention of metalworking applications. Luigizanasi 04:54, 3 November 2005 (UTC)[reply]

Table Saw vs. Cabinet Saw

The entry for Table saw addresses Cabinet saws as a subset of table saws, which is how I always understood them. However, this entry suggests that a cabinet saw is a similar but different machine. Anyone disagree with this? cbustapeck 19:30, 22 July 2006 (UTC)[reply]

Kerf

The current definition seems to include serrated knives:

A saw is a tool for cutting wood or other material, consisting of a serrated blade (a blade with the cutting edge dentated or toothed) and worked either by hand or by steam, water, electric or other power.

I propose changing it to

A saw is a tool for cutting wood or other rigid material consisting of a serrated blade which removes material to make way for the remainder of the blade.

That is, it seems like a saw is defined by the fact that it removes its kerf; the only other way to cut hard materials is with an axe or a shear. Thoughts? —Ben FrantzDale 15:36, 10 August 2006 (UTC)[reply]

Is there an important difference between a serrated knofe and a saw? ike9898 16:33, 10 August 2006 (UTC)[reply]

Coping Saw vs Jigsaw

Do americans call thier motorised hand held Jigsaws Coping Saws? - the coping saw is stricly for the unmotorised version.Erlyrisa 07:47, 18 October 2006 (UTC)[reply]

Not that I know of or in any of the references I have seen. It's either jigsaw, saber/sabre saw or bayonet saw. Luigizanasi 14:56, 18 October 2006 (UTC)[reply]

Who invented the saw?

Did the Romans have access to the saw? Were the pyramids built without the saw? Was it invented in the bronze age, or the iron age? This article about Norse Longships declares they were constructed using axes, as the "Vikings" lacked the saw. Why would they not have it, who invented it, and when?

Second paragraph wrong on a number of counts

The second paragraph talks about the "set" of the saw is:

In a modern serrated saw, each tooth is bent to a precise angle called its "set". The set of the teeth is determined by the kind of cut the saw is intended to make. For example a "rip saw" has a tooth set that is similar to the angle used on a chisel. The idea is to have the teeth rip or tear the material apart. Some teeth are usually splayed slightly to each side the blade, so that the cut width (kerf) is wider than the blade itself and the blade does not bind in the cut.

This is wrong on a number of counts:

All saws are serrated; if a saw weren't serrated, it would be a knife
The "set" of the saw has nothing to do with crosscut versus rip; the set is the "splay" described (somewhat confusingly) in the last sentence
The difference between crosscut and rip saws is the rake angle (how far the leading edge of each tooth tips back from being perpendicular to the edge of the blade) and the presence or absence of fleam or bevel (the sharp side angle on each crosscut tooth)

Except that... not all Saws are serrated? Abrasive Saws, for example, use an abrasive edge, rather than a serrated one (this is actually stated in the article). I can't chime in on the rest of what yous aid though. Pyrotics (talk) 20:40, 10 August 2008 (UTC)[reply]
