I have finished a toe-up sock!  I must admit, it isn't knit, it is crocheted. However, it is a toe-up sock. I found the pattern on www.CrochetMe.com and it worked up fairly quickly in Hobby Lobby's Snowflake wool blend which is light weight # 3 yarn.  I used a size F/3.75mm  and an E/3.5mm hook.  The smaller hook was for the ribbing at the top of the leg.
