https://wiki.project1999.com/Embalmers_Skinning_Knife will always be useful in your leveling up process, until you can replace them with the better versions. With an SK, reducing downtime is the key, especially if you solo a lot. Those two items will also maintain their price, when you do replace them.
If you plan on buying just Silver Chitin Hand Wraps + Wedding Ring Pair + Jboots + Noct Blade and Atrementous shield, you are already spending over 10k. It shouldn't be too hard to farm another 10k for a regen BP and skinning knife, eventually. This is especially true when your SK is around level 25+, you can start killing halfling guards for cash.
