Having said that, you probably need to replace a rotary cutter blade when it skips threads as you use it. There are "sharpeners" for blades, but my experience with them has not been noteworthy. I just look for the 50% off sales and stock up so I have backups. I never know when my frustration with skipping will reach a "tipping point". :) As for shears/scissors, you won't need to replace them, but may need to have them professionally sharpened. If you take care of them, it will be a while before you need this done. Again, when the shears aren't cutting well is when you should consider this. Sewing machine needles take more (ab)use than hand needles do and the stitches may show if the needle isn't sharp. Mostly with hand needles, the time I have to replace them is when they bend.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1957436908214579302.post-51095428020537316942010-02-09T09:57:13.420-08:002010-02-09T09:57:13.420-08:00Quick question...how do you know when you need to ...Quick question...how do you know when you need to replace any given cutting implement? I don't think I'm at a point of needing to just yet, but then again I'd probably keep using needles for years if you didn't tell me to replace them every 6 sewing hours. :-)Kathttps://www.blogger.com/profile/10295095982479294130noreply@blogger.com
