Thanks for your test Erica! I have the Izula in Venom Green with a black and an orange sheath. Here in Germany they are not very cheap, but they are worth it! Greetings Stefan 🙂!
I have gone down this rabbit hole already, so maybe I can save you some time. I think one steel type taking one type of edge finish better than another is largely a myth. You can "glass out" an edge on any type of steel just as you can leave any edge toothy. What really matters is what you're cutting and what your mechanics are. Generally, polished edges favor push cutting, and toothy edges favor pull cutting. Wood working is largely push cutting, which is why those guys all love polished edges and why you found your feathers to be easier on the candiru. Chopping is one big push cut too. All my axes and outdoor "bushcraft" knives get polished edges for that reason. General EDC and anything I use in more of a "pull cut" slicing motion stays in the 400-600 grit range. Most hunters I know prefer toothy edges for skinning, for example. There are a few good ways to test your edge finish. Cutting magazine paper is one. If you glass out an edge, it will have trouble biting in at the paper edge with a light pass with the blade held straight vertical and slicing down, despite being stupid sharp. In contrast, the toothy one will have no issue. Paper towel test will show this even better. Very sharp polished edges can have trouble slicing paper towels. You can also rub a cotton boll along the length of the edge. A nice toothy sharp apex will grab hairs, and a highly polished edge will not. One thing I love to do is use rods to create a microbevel. Sharpen as usual, de-burr on the rod and give it a few more passes to create one. This will allow for super easy touch-ups to change performance on the fly. Use a very fine ceramic rod to maintain polish when you want it, or a medium grit diamond rod to establish tooth. You can switch back and forth with a few passes and really optimize your cutting performance quickly.
IMO toothy edges definitely have their place, like for cutting things like rope or cardboard. But for things like wood or meat, I much prefer a polished edge. I've got an Izula 2 that I run 17 dps and polished because I use it as a skinning knife sometimes. Cheers, E!
Interesting video, I really like putting the two knives from the same maker and same steel against each other. I was surprised that the highly polished edge performed better. Thanks for sharing and spending the time to make these videos. God bless you and your family.
Would love to see more tests, expected finer.shavings with refined edge similar.to tpi on a saw or sandpaper or sharpening stones, i hope you get to test on some woven fibers, natural and synthetic with draw cuts too, paracord can get tough at times, hope to see more of this with more knives and different media materials to cut and different cutting/slicing motions👍👍👍👍
Straight razors are high carbon steels usually and range from an 8k finish to rediculously fine stones. Hair is suppose to be the same consistency as copper so a higher polished edge might be the way to go.
Looks like the bevel angles are different. Do you remember the angle you put on the little guy? And do you know what the angle was for the bigger blade? Larrin is a big proponent for bevel angles. Looks like you did a beautiful job on the little one. Good video. Thanks
I didn’t measure the DPS. I left it the same as the factory one on the Candiru. It may look wider because it’s polished and less convexed than the factory. I just followed what it already had. Thanks so much for watching!
Would the powder coat matter? My Izula 2 does not have one. It has a forced patina from the factory. Couldn't you bring it up that high polish and keep the factory convex intact? Did the candiru come with that sheath?
Icy edges can be a bit slippery depening on the work you're doing. Wood work I like a good bite so even if I polish an edge ile run it on a rougher rod to give it some teeth esp convex grinds. I mainly work wood 99% of the time so thats a big difference for some folks. That's why I dont fuss with steel all that much . 1095hc, 80CrV2, D2 are my faves but I do like 14C28N its good budget stainless steel.
Hi Ms E. I could hear the difference in edges on both the cardboard and on your stick. I'm 54 years old and hard of hearing. You enjoy your day tomorrow over east. Take care.🇺🇲🔪🌲🔥
This is interesting but I think it is a better comparison of hand sharpened and factory sharpened knives. I know it’s easy for factory edges to be slightly burned or just not perfect in some way. It may behoove you to sharpen the izula some and remove some of the edge while putting your coarser edge on it and compare them again after touching up the other as well. This will probably also help the BTE to be even more similar and make the edge bevel angle more similar as well. Or at least make that variable more of a constant. As it is I think there’s too many confounding variables to say it’s an accurate comparison of a mirror edge versus a coarse edge. As you said it isn’t scientific and it is subjective but I think it’s a good way of figuring out what you personally prefer and showing people that it’s okay to like edges in different ways on different steels and grinds. Going back to the comment section of the one video about people liking different design, HRCs, etc. Over all definitely a fun video and showing the difference (or at least noting the visible difference) if the curls is interesting. I wouldn’t think the edges would be so dissimilar to cause that much of a difference there so that was interesting. I may have to do some testing on feather sticks with different coarseness edges myself to see if I can see a difference as well.
@@ericasedc of course! Also I’m sorry if I am ever too critical or anything like that. I tend to play devils advocate. If I ever get to be too much please don’t let what I say bother you. It is a great video and I hope you have a wonderful day! I look forward to the next one. Also I didn’t comment about this on the last video and sorry for that but I hope everything with the Job situation works out for you as you want it to! :)
Now see i though i smelt something 😂 Just kidding just kidding. My ankles would be screaming sitting like that on the concrete 😬 I know both knives have to be super sharp but man that green just speaks to me. Really love the high polish on it. Really pops better in my opinion than the orange. Great test. You have such a creative mind with all your testing. You can really break knives down on a whole other level. 👍👍
Lol @ "sorry if the whole barefoot thing bothers you" hahaha it doesn't get more barefoot than actually not wearing shoes in the asphalt driveway lol! People probably getting freaked out as if Erica hasn't cut shit in the driveway barefoot since she was 5 years old LOL. You think she WANTS to chop off a toe??? She's a pro, people!!! Calm down!!! But I totally hear you!! If I can help it, I'm not wearing any shoes at all!! There's nothing better than the feel of grass or earth on your feet, homie!!! Holy fuck that sounded weird haha!! It's true, tho!!! I never wear shoes in or around the house!! People who do are freaking weirdos!!! They probably wear socks to bed too!!! Great video, Erica!!! ❤
