Shinwa H-3412A 6" 150 mm Rigid English Metric Zero Glare Satin Chrome Stainless Steel E/M Machinist Engineer Ruler/Rule with Graduations in 1/64, 1/32, mm and .5 mm

This is a fantastic rule to follow. I've bought a lot of rules in the last two years. Some of them are excellent, while others are less so. One of the most vexing aspects of some rules is how they mix English and metric units on the same side. As a result, neither edge can be used to measure anything. For instance, if you want to inspect something from both the left and right sides. You're not going to be able to do it. That is, once again, extremely irritating. On BOTH edges of any side of the rule, the same unit of measurement is used. The one side is written in English, and the other is written in metric. That alone qualifies this rule as exceptional in my opinion. There is, however, much more. br>br> This rule has a fantastic finish to it. It has a matte finish that prevents fingerprints from showing up. The text is extremely clear and easy to read. This rule is also made of heavy stainless steel, which is a unique feature. There isn't much flex to skew a measurement's accuracy. br>br>It goes without saying that this is my favorite and best rule.

I do a lot of technical sketches when I'm not at my desk, so compact rulers help me stay mobile and fit into my moleskin note books, unlike a full-size ruler, which in many cases sticks out at least 6 inches from the mole skins page. It's just the right length and width to fit into a pencil case, so I can toss it in there with the pencils and go. A 0 can be seen in the image. For a scale reference, I used a 5mm mpencil. When compared to the pencil lead, notice how fine and clear the ruler's marks are. In MM, one side is metric, and the other side is zero. Markings are 5mm apart. The opposite side is in inches, with markings for 32nd and 64th. The 1/8 and 1/16 markings can still be read clearly. The inclusion of the ruler slip case was a nice touch. This makes it easier to carry it around in a pocket or other location where the metal ruler won't harm other items. Because it has pointy corners, the slip case helps to protect it. The corners must be pointed so that the ruler can be squared up on its ends and measured from them without having to do any math later to account for an end gap between the end and where the ruler marks begin. It's only 6in (150mm) long, but it's as thick as a full-size metal ruler, so there's no risk of it bending accidentally. It comes at a reasonable price.

I use them on a daily basis and always have at least one with me. This one has recently become my favorite; I like to have a rule on hand at all times, so I have a lot of them stashed away in places where I can quickly grab one. I like having a rule that I can cut down to fit whatever I'm carrying- such as a wallet, notebook, or coin purse I like to have one that has both metric and imperial markings on the reverse side. However, if each measurement standard starts at a different end of a rule, you can't cut either end without losing the rule's beginning. Because they both begin at the same end on this one, I can cut off the other end without losing the beginning of either. Furthermore, by flipping it over, you can quickly switch between metric and imperial units without having to swap end to end. It is therefore easier to use, even if you do not intend to shorten it. The satin-finish The chrome finish is stunning and makes reading a breeze. The lettering is so dark that I initially assumed it was just painted on and that it was a low-cost item, but I was mistaken. They have a very precise and shallow etch with ink inside the etch, which I discovered. This is a very high-quality product. Other manufacturers make less expensive versions with the same graduations, but they aren't as accurate or as easy to read as this one. These are things I wish I had discovered years ago. In fact, I'm currently ordering more of them, which I intend to reduce in size.

This was bought to calibrate my research microscope's lowest power magnifications. I have a nice, accurate 1 cm micrometer slide that I use for higher powers, but I prefer to calibrate across the field of view when the field of view is longer than 5 cm. I have a variety of rulers that range from to almost. Over a 10 cm distance, the difference is 5 mm. This and a Mitutoyo rule were the two rules I purchased. Both calibrations match my micrometer slide at that scale, and they are spot on with each other. This rule is a little more flexible than the Mitotoyo, but it's still quite rigid. For my calibration purposes, I prefer it over the thicker ruler. Despite the fact that no rule of this size will have only hair width measurement lines, these are fairly narrow and served as a useful calibration tool.

I have several 6" scales, but I needed one with a metric rule. br>br>I have several 6" scales, but I needed one with a metric rule. With 1 and 0, this one has proven to be quite good. On one side, there are 5mm markings, while on the other, there are 1/32" and 1/64" markings. The 1/64" markings agree with a scale that I've used for years and found to be very accurate within the limits of my vision. If I had one complaint, it would be that because the length is not a precise number of cm or mm, only one end of the metric scale is convenient for measurements. However, this is due to the obverse's imperial scale, as 6" equals about 152. 4mm. I don't blame the scale for this, but a true 150 mm scale might be more practical for metric users.

This Shinwa is the closest thing to a Mitutoyo ruler, which is high praise, and it is fantastic. The very large whole-foods market is one of my favorites. Number markings in the Shinwa style, which Mitutoyo used to use but has since abandoned in favor of finer markings. Both approaches are acceptable, but I prefer the Shinwa's larger style. br>br>At bad lighting angles, the Shinwa is significantly less legible than the Mitutoyo, which appears to have much blacker markings and a more matte surface finish, creating higher contrast, but the text really pops when you angle the Shinwa to catch the light in your eye. br>br>It's also a little less rigid than the Mitutoyo, but not enough to notice in practice. This ruler is precisely sized at 6 in to within a thou, and probably to within half a thou, as you can see in the photo. That's quite impressive, and it places this among the best on the market once more.
